Below, each embodiment of image forming apparatus of the present invention is described with reference to the accompanying drawings.Among the figure, represent identical parts, it is not repeated in this description with identical label.
First embodiment:
Fig. 1 represents the primary structure of an image forming apparatus.This image forming apparatus is a kind of information according to input forms the image of for example required character or figure and so on the surface of record carrier 7 a equipment.For example, this image forming apparatus can be used as and is furnished with the sense station 21 of reading the image that will form from original paper 8.As shown in Figure 1, in this image forming apparatus, charging zone 11, exposure region 20, developing district 3, transfer area 4 and eliminate that district 5 is arranged in turn by circumferencial direction can be around photosensitive drums 13 that its central axis rotates, and photographic fixing district 5 is arranged on the transfer passage of record carrier 7, record carrier 7 passes through between the outer circumference surface of transfer area 4 and photosensitive drums 13.The developing district 3 of existing equipment shown in Figure 5, transfer area 4 and photographic fixing district 5 can be used as the developing district 3 of this image forming apparatus, transfer area 4 and photographic fixing district 5.Equally, flexible material for example paper can be used as record carrier 7.
Fig. 2 A and 2B represent the charging device and the scavenge unit 12 of this image forming apparatus respectively from principle with the form of skeleton view and sectional view.In Fig. 2 A and 2B, photosensitive drums 13 is made of the cylindrical shape insulator that forms a closed-loop.Photosensitive drums 13 is rotated around the center line of cylinder.Owing to rotate, photosensitive drums 13 is moved along closed-loop.On the outside surface of the closed-loop of photosensitive drums 13, form the photographic layer 14 that constitutes by semiconductor layer.Charging device 11 is given the surface charging of photographic layer 14.Charging device 11 comprises charging X-ray tube 15a and 15b and electric field bringing device, charging X-ray tube 15a and 15b be arranged on the outside of above-mentioned closed-loop and with x-ray irradiation the time air on the ionization photographic layer 14, the electric field bringing device is guided to the surface of photographic layer 14 by the gaseous ion that applies electric field ionization is produced.
The electric field bringing device comprises an external stability electrode 16a and an internal fixation electrode 16b, and each electrode all is made of sheet metal, and the first power supply 17a and second source 17b are arranged.External stability electrode 16a is arranged on the outside of closed-loop on the surface of photographic layer 14, and internal fixation electrode 16b is arranged on closed-loop inside, so that the photosensitive drums through comprising photographic layer 14 13 is in the face of external stability electrode 16a.The first power supply 17a with 0 to V+[V] positive polarity voltage impose on external stability electrode 16a, and second source 17b is with V-[V] reverse voltage impose on internal fixation electrode 16b.By applying voltage, externally form an electric field that points to internal fixation electrode 16b from external stability electrode 16a between fixed electorde 16a and the internal fixation electrode 16b.
Charging X-ray tube 15a and 15b are arranged on two corresponding end of rectangle external stability electrode 16a, in order to give the surface charging of photographic layer 14 equably, each charging X-ray tube 15a and the preferably microscler X-ray tube of 15b in this embodiment, rather than by a plurality of brachmorphy X-ray tubes of vertical arrangement of drum.X-ray emission hole 15al and the 15bl of charging X-ray tube 15a and 15b are that capillary is tubular, therefore, all have directivity from every beam line of transmitting aperture 15al and 15bl emission.That is, when the air between charging X-used in cathode-ray tube x-ray irradiation internal fixation electrode 16a and the photographic layer 14, the X-ray of ejaculation is parallel with photographic layer, can not impact photographic layer.
Here, as long as charging X-ray tube 15a and 15b be emission X-ray between fixed electorde 16a and the photosensitive drums 13 externally, not necessarily leave no choice but they are connected to external stability electrode 16a, whether parallel without limits to the X-ray of being launched with the outside surface of photosensitive drums 13.The X-ray that charging X-ray tube is launched can point to its center from the outside of photosensitive drums 13.
On the other hand, in scavenge unit 12, eliminate X-ray tube 12a in the outer setting one of the closed-loop of photosensitive drums 13.Eliminating X-ray tube 12a is elongated X-ray tube equally, to the surface emitting X-of photographic layer 14 ray 19.The energy of eliminating the X-ray that X-ray tube 12a and above-mentioned charging X-ray tube 15a and 15b launched is 1 to 20Kev.Both sides eliminating the X-ray tube vertically are provided with a sheet metal 12b along it, and sheet metal 12b is a ground connection.Equally, the rotation direction in photosensitive drums 13 is provided with a brush remover 12c near eliminating X-ray tube 12a.
As shown in Figure 1, exposure region 12 has the sense station 21 of reading the image that will form from original paper 8.Exposure region 20 is that the surface of the photographic layer 14 that is recharged device 11 chargings is exposed to the open air under light, to form and the visual zone of electrostatic latent image accordingly that will form.For example, exposure region has sense station 21, laser system 22 and irradiation mirror 23.Sense station 21 comprises support plate 21a, irradiation light 21b and a plurality of reflective mirror 21c, and like this, form that just can light signal is read the image that will form from original paper.Promptly, irradiation light 21b and reflective mirror 21c are set below transparent support plate 21a, so that 21a moves along support plate, like this, after being placed on original paper on the support plate 21a, along with moving when irradiation light 21b sees through support plate 21b irradiation original paper 8 of irradiation light 21b and catoptron 21c, will read in turn with the form of light signal at original paper 8 lip-deep images.Equally, by the laser system 22 and the irradiation mirror 23 of pre-orientation, these light signals shine on the outside surface of the photosensitive drums 13 between charging device 11 and the developing district 3, thereby form electrostatic latent image thereon.
Below, with reference to Fig. 3 A and 3B charging mechanism in the above-mentioned image forming apparatus is described.Among the figure, the parts identical with 2B with Fig. 2 A are represented with identical label, are not repeated in this description.
When the first power supply 17a and second source 17b respectively with 0 to V+[V] positive polarity voltage and V-[V] reverse voltage when imposing on external stability electrode 16a and internal fixation electrode 16b, externally produce the electric field that an external stability electrode 16a points to internal fixation electrode 16b between fixed electorde 16a and the internal fixation electrode 16b.In this case, surperficial parallel from the X-ray 24 of X-ray tube 15a and 15b emission and photographic layer 14.When using x-ray irradiation,, thereby on the surface of as shown in Figure 3A photographic layer, form the charged ion that has positive polarity and negative polarity with the air ionization between fixed electorde 16a and the photographic layer 14 externally.
In addition, owing to externally there being electric field to form between fixed electorde 16a and the internal fixation electrode 16b, photosensitive drums 13 has polarity.Owing to polarity is arranged, shown in Fig. 3 B, on the interior and excircle of photosensitive drums 13, occurs positive charge (+) and negative charge (-) respectively.Therefore, in the gaseous ion that with x-ray irradiation the time, produces on the surface of photographic layer 14, under the attraction of the electrostatic force of the negative charge (-) that is in addition producing on the excircle of photosensitive drums 13 under the effect of electric field that produces between electrode, the gaseous ion of band positive polarity electric charge is guided to the surface of photographic layer 14, thereby make the surface of photographic layer 14 be with positive polarity.Because above-mentioned X-ray tube 15a and 15b is elongated X-ray tube, photographic layer 14 lip-deep air are subjected to the uniform irradiation of X-ray, thereby evenly produce gaseous ion in the air between X-ray tube 15a and 15b.Therefore, the surface of photographic layer 14 lotus (+) that becomes positively charged equably.On the surface of photographic layer 14 charged polarity opposite with the polarity of the voltage that imposes on internal fixation electrode 16b.
In addition owing to can control the magnitude of voltage that imposes on the external stability electrode, just arbitrarily the surface of sense of control photosphere 14 with positive charge (+) quantity of electric charge Q.Below, described with reference to Fig. 4 A to 4B.
At first, shown in Fig. 4 A, to the sheet metal 32 emission X-rays 33 that are L from its distance, measure the surface potential of sheet metal thus from X-ray tube 31.Here, the metal shell 31a that constitutes Ta (tantalum) the hole 31b of X-ray tube 31 and emission X-ray is not an earthing potential, but applies a predetermined voltage Vo to it.Therefore, the target voltage of X-ray tube 31 is exposed to the outside as the X-ray tube.Measurement result is shown in the curve map of Fig. 4 B.The surface potential (V) of the horizontal ordinate among the figure and ordinate difference express time [t] and sheet metal 32.As shown in the figure, the surface-potential stabilization of sheet metal 32 is at current potential V[V].When being stabilized in electric V[V＜Vo at this experiment situation lower surface current potential] time, because the area of Ta hole 31b that is applied with voltage Vo is less than the surface area of sheet metal 32, identical and when being set parallel to each other, the surface potential of sheet metal 32 should be Vo in theory when the area of hole 31b and sheet metal 32.
Therefore, shown in Fig. 4 D, when an insulator 36 being inserted between the plate 34 and 35 that its potential difference (PD) shown in Fig. 4 C is Vo and between insulator 36 and sheet metal during a branch of X-ray 37 of emission, electric charge is with on the surface of insulator 36, therefore, the current potential on the surface of insulator 36 is Vo in theory.Therefore, the thickness of supposing insulator 36 is d[m], its surface area is s[m
2], the equation below available represent insulator 36 the surface with the quantity of electric charge:
Q＝ε-ε
o-(s/d)·Vo
So, because of the voltage Vo and the thickness d of insulator 36 is adjustable, so the quantity of electric charge Q of the surface band of insulator 36 is controllable.Promptly, when hypothesis insulator 36 is photosensitive drums 13 among this embodiment and photographic layer 14, because it is adjustable imposing on the voltage of external stability electrode 16a and photosensitive drums 13 and photographic layer 14 one-tenth-value thickness 1/10 separately, so the quantity of electric charge Q of the surface band of photographic layer 14 can arbitrarily control.Equally, when the polarity (+) of considering used toner and (-) selection impose on the polarity chron of the voltage of external stability electrode 16a and internal fixation electrode 16b, can choose at random the polarity of electric charge of the surface band of photographic layer 14.
Adopt this method, can give the surface charging of photographic layer 14 by the charging device 11 of image forming apparatus.
Below, with reference to Fig. 1 and 2 B, the elimination mechanism of the latent image electric charge in the image forming apparatus of this embodiment is described.
In Fig. 1, because the rotation of photosensitive drums 13 forwards the irradiation that air on the photographic layer 14 of eliminating district 12 directly is subjected to the X-ray 19 of X-ray tube 12a emission to from transfer area 4.Air on the photographic layer 14 is subjected to the irradiation of X-ray 19 and ionization, thereby produces gaseous ion.In the gaseous ion that produces like this, the gaseous ion neutralization of band positive polarity has had the electric charge of the contrasting power of negative polarity, and stays on the surface of photographic layer 14.Simultaneously, in photographic layer 14, produce a carrier from the X-ray 19 of X-ray emission, thus neutralization and eliminate the latent image that in photographic layer 14, forms.The contrasting power of staying on the photographic layer 14 that is neutralized is brushed remover 12c elimination, thereby makes the cleaning surfaces of photographic layer 14.
Below, will the operation of the image forming apparatus of this embodiment be described.
At first, in Fig. 1, original paper 8 is placed on the support plate 21, make have the image that will form the surface down.In this case, start this equipment, when the irradiation light 21b of exposure region 20 bright the time, irradiation light 21b and reflective mirror 21c move along original paper 8.At this moment, the light that sends from irradiation light 21b reflected by original paper 8 and as light signal by reflective mirror 21c, lens combination 22 and irradiation mirror 23 are guided photosensitive drums 13 into, so that the lip-deep photographic layer 14 of the photosensitive drums 13 shown in irradiation Fig. 2 B.On the other hand, when the surface charging of the photographic layer 14 of giving photosensitive drums 13 with charging device 11, it rotates with the rotation of photosensitive drums 13.
When the photographic layer 14 of such charging forwards the exposure position of exposure region 20 to, under the irradiation of the light of launching from exposure region 20, on the surface of the photographic layer 14 that charges, form visual electrostatic latent image accordingly in turn with original paper 8.Then, when photographic layer 14 forwards developing district 3 to, have the position that is attached to this electrostatic latent image with the contrasting power of the toner of the polarity opposed polarity of electrostatic latent image.Though what adopt usually is the black contrasting power, also can adopt the contrasting power of other color.When photographic layer 14 continues to forward transfer area 4 to, to form rotational synchronization ground input between photosensitive drums 13 and transfer area 4 of the record carrier 7 and the photographic layer 14 of image thereon, because be subjected to the effect of the electrostatic force of transfer area 4, the contrasting power on the photographic layer 14 is transferred on the record carrier 7.After transfer operation is finished, record carrier 7 is transported to photographic fixing district 5, by heating, contrasting power is fixed on the record carrier 7 in photographic fixing district 5, form needed image thereon.On the other hand, after the contrasting power transfer printing, and in photographic layer 14, leave contrasting power, it is removed reliably and removes, make photographic layer 14 recover its original state with above-mentioned scavenge unit 12.Then, after giving photographic layer 14 chargings with charging device 11, repeated exposure, developing, transfer printing and removing step are to form image.
Second embodiment:
Although as insulator photographic layer 14 is rotated with cylindrical shape photosensitive drums 13 according to aforesaid first embodiment in image forming apparatus, the reply insulator without limits.For example, can use the film band of the insulating element making that forms a closed-loop as insulator.In this case, can form photographic layer 14 on the outside surface of the film band of closed-loop, the shape of this band should make it move along closed-loop.Equally, in the above-described embodiment, charging device 11 and scavenge unit 12 can be arranged on the outside of closed-loop.Adopt this structure, can obtain the effect the same with first embodiment.
The 3rd embodiment:
Although form photographic layer 14 on closed-loop photosensitive drums 13 in the image forming apparatus of first or second embodiment or the film band, the material that forms photographic layer 14 thereon is not limited to the closed-loop parts, and can be plate shaped.For example, can form photographic layer 14 on a surface of the plate of making of insulator, it moves on in turn and is respectively equipped with charging device 11, exposure region 20, developing district 3, the position of transfer area 4 and scavenge unit 12, thus in photographic fixing district 5 image is fixed on the record carrier 7 of input transfer area 4.This result also produces the effect identical with first embodiment, and here, above-mentioned plate also can be an arc.
The 4th embodiment:
