Next, exposure is performed corresponding to the recorded image using the exposure device 3 including an optical system using a laser light source, a light emitting diode (LED) light source, or the like. By this exposure, the surface potential of the exposed portion of the photoreceptor is lowered, and an electrostatic latent image is formed on the photoreceptor 1.

った問題点がある。When a one-component magnetic toner is used, when it is transferred to a recording paper made of plain paper, the charge held by the toner leaks through plain paper with low resistance (resistance value of 10 12 to 10 13 Ω-cm). The transfer efficiency is significantly reduced. Therefore, when the one-component magnetic toner is used, there is a problem that it is necessary to use a recording paper (10 14 to 10 16 Ω-cm) whose surface has been subjected to high resistance treatment.

にしたものである。That is, the image recording apparatus of the present invention does not require a high voltage power source like a corona discharger, uses a photoconductor having a three-layer structure of a transparent substrate, a transparent conductive film, and a photoconductive film, and uses a light source for image exposure as a photoconductor. It is placed opposite to the developing machine with the photomask sandwiched between them, and image exposure is performed from the side of the photoconductor substrate at the same time as development to obtain a clear printed image and to reduce the size of the entire device. By collecting the toner by means of (1), the efficiency of collecting the toner is improved and the use cost of the consumable parts is reduced.

の磁力で残留トナーが確実に回収でき得るようになる。Further, a light irradiation unit for irradiating the photoconductor is provided opposite to the transfer unit, and the photoconductor is irradiated with light to reduce the resistance of the photoconductor to facilitate the movement of the charged toner, and a special high resistance treatment is performed. Transfer recording can be easily performed normally without using recording paper. By irradiating the photoconductor after transfer using a charge elimination lamp, the trapped charges on the photoconductor are removed, and the residual charge on the photoconductor is weakened to the binding force to the photoconductor, so that the residual charge is easily separated from the photoconductor. By so doing, it becomes possible to reliably collect the residual toner by the magnetic force of the magnetic brush developing machine.

トナー像15が引き寄せられて付着する。Use the power supply 14 of the developing machine 12 to connect the sleeve 12A of the developing machine 12 to
A developing bias voltage of about 00 to 300 V is applied, and the exposure device 13 shown in FIG. 1 is used in accordance with the image pattern from the rear surface side of the photoconductor 11, that is, the substrate 11A side so as to face the set position of the developing machine 12. Exposure is performed as shown by arrow B. Here, the non-exposed portion of the photoconductive layer 11C is a dimension in the thickness direction of the photoconductive layer 11C,
Alternatively, the capacity is made sufficiently small depending on the material so that the charged toner image 15 does not adhere. On the other hand, in the exposed portion, the resistance value of the exposed portion is reduced by the irradiation of light, and the transparent conductive layer 11 generated by the light irradiation is generated.
The charge 23 of B reaches the surface of the photoconductive layer 11C, and the capacity of the part of the photoconductive layer 11C which is irradiated with light apparently becomes large, so that the charged toner image 15 adheres to that part, and this photoconductive On the surface of the layer 11C, a negative charge 23 having the opposite polarity to the charge of the charged toner image 15 is trapped, and the trapped charge 23 attracts and attaches the charged toner image 15.

なる。As shown in the figure, the recording paper is placed on the charged toner image 15 on the photoconductor 11.
A transfer device 17 made of a conductive rubber roller is provided via 16, and a negative voltage having a reverse polarity to the developing bias voltage is applied to the transfer device 17 by using a power source 18. Further, by facing the position of the transfer unit 17 and irradiating light from the transparent substrate 11A side using the exposure device 19 in the direction of the arrow C, the photoconductive layer 11C becomes in a low resistance state, and the electric charges are easily moved. , Transparent conductive layer
Positive charges from 11B are injected into the charged toner 15. The charged toner 15 into which the positive charge has been injected is transferred to the transfer device 17 and the transparent conductive layer.
The electric field between 11B and 11B causes transfer to the recording paper 16.
次に前記第１図に示すように定着器20を用いて帯電トナ

と同時に次の記録サイクルに於ける像形成が行われる。On the other hand, after the toner image 15 is transferred onto the recording paper 16, a residual toner image 21 is formed on the photoconductor 11. This residual toner image 21
Holds the electric charge, and at the time of transfer, the photoconductive layer 11C
The electric charge remains inside. Therefore, the residual toner image 21 is difficult to remove from the photoconductor 11. Therefore, the charge of the residual toner image 21 and the charge in the photoconductive layer 11C are removed by irradiating light from the transparent substrate 11A side using the charge eliminating lamp 22. The residual toner image 21 from which the charge has been removed has a weaker binding force to the photoconductor and is recovered by the magnetic force of the developing device 12. At the same time when the residual toner image 21 is collected, image formation is performed in the next recording cycle.

録画像が形成できる。According to such an image recording apparatus of the present embodiment, image recording is performed by four steps of an image forming step, which simultaneously performs image exposure and image development, a transfer step, a fixing step, and a charge eliminating step. A recorded image can be formed by a simpler process than that in an apparatus.

が防止できる。Further, the photosensitive member is irradiated with light and transferred while injecting charges into the toner, so that recording can be performed on plain paper instead of recording paper subjected to a special high resistance treatment. Further, after the transfer, the toner remaining on the photoconductor is discharged and collected in the developing machine, so that there is no toner loss and the use efficiency of consumable parts is improved. Furthermore, since no corona discharger is used, a high voltage power supply of several KV is not required, and ozone that is harmful to the human body can be prevented.
次に本発明の第２の実施例につき、第４図を用いて説明

る。このように本実施例は、第１の実施例に比してトナ
ーの電荷をより速く除電する効果がある。The residual toner 21 on the photoconductor 11 is forcibly discharged by the AC corona discharger 31. On the other hand, the light irradiation of the static elimination lamp 22 causes the photoconductive layer 11C to have a low resistance, and as a result, the residual charges in the photoconductive layer 11C are easily moved, and the residual toner 21 is recovered by the magnetic force of the magnetic brush developing machine 12. To be done. As described above, the present embodiment has the effect of discharging the electric charge of the toner faster than the first embodiment.
また本実施例の他の転写ローラの代わりとして、コロナ
放電転写器を用いた場合に於いても、従来の電子写真装
置における如く、一様帯電コロナ放電器を用いていない
ので、高電圧電源を減らせる効果がある。Further, even when a corona discharge transfer device is used as a substitute for the other transfer roller of this embodiment, a uniform charging corona discharge device is not used as in the conventional electrophotographic apparatus, so a high voltage power source is used. Has the effect of reducing.
更に本実施例の他に感光体をベルト（シート）状にして
移動させても良い。また光導電膜は本実施例で用いた有

部品に要するコストが低下する効果も併せて生じる。As described above, according to the image recording apparatus of the present invention, since the developing step and the exposure step are performed in the same step, the steps required for image recording can be shortened, the apparatus can be downsized, and special high resistance treatment can be performed. There is an effect that transfer recording can be performed on ordinary recording paper instead of the applied recording paper. Further, since the residual toner after the transfer is recovered by the developing machine, the recovery efficiency is improved, and the cost required for consumable parts such as toner is also reduced.
