Abstract

PURPOSE: To eliminate the need for corotron for uniform charging and make possible copying through one turn of a photoreceptor by successively performing the copying processes including electrically dividing the conductive substrate of a photosensitive drum and uniform charging by the application of bias voltage on every divided portion.
CONSTITUTION: The conductive substrate 2 of a photosensitive drum laminated with a photosensitive layer 3 is trisected electrically by insulators 5... Respective processes of uniform exposing by a light irradiating device 10, uniform charging by a bias electrode 6, latent image forming by an earth electrode 81 and an original exposure device 12, developing, and image transferring to copying paper are successively performed on these divided conductive substrates 21W23 for every substrate. With this constitution, the need for corotron for uniform charging is eliminated and there is no degradation of coratoron wire and no effect of ambient environments, thus even when the photosensitive layer of the photosensitive drum is insulated with an insulating layer or is not, the copying is accomplished in the same process, and the copying may be completed through one turn of the photosensitive drum.
