性を有するものである必要がある。The insulating layer may be either transparent or opaque, but opaque is preferable to prevent the influence of stray light. The toner may be a single-component magnetic toner, or may use magnetic powder as a carrier; however, in any case, it must have a certain degree of conductivity.
本発明方法に依れば、感光層が光導電性絶縁体であれば
良く、電荷保持性や持続導電性を必要としないことによ
り感光層の材料の制限が少な込。According to the method of the present invention, the photosensitive layer only needs to be a photoconductive insulator, and charge retention and sustained conductivity are not required, so there are fewer restrictions on the material of the photosensitive layer.

材料に制限がない。又従来のように帯電器を必要とせず
従ってコロナ放電生成物による二次障害がない。Furthermore, since this photosensitive layer does not come into direct contact with the outside air or parts during the cleaning process, there are no restrictions on the material of the photosensitive layer with respect to deterioration or wear. Further, unlike the conventional method, there is no need for a charger, and therefore there is no secondary damage caused by corona discharge products.

た場合特に便利である。Exposure and development occur at the same time, and the insulating layer on the developing side may be opaque, and only the exposed portion on the back side of the back side needs to be shielded from stray light, so there are no restrictions on the selection of the insulating layer material.
Also, the ability to use an opaque insulating layer means that most parts of the equipment
11 bright operations are possible without the need to block out light. Furthermore, if development is carried out using a single-component toner while maintaining a balance with the magnetic force, cleaning and reproducing images occur simultaneously during development due to back side exposure, which is particularly convenient when applied to a copying machine without the need for a cleaning device.
