ABSTRACT:
An electrophotographic process using a photosensitive member having an amorphous silicon photosensitive layer, includes uniformly charging the photosensitive member, and exposing the photosensitive member to information light to form an electrostatic latent image, developing the electrostatic latent image using a developing device selected from a plurality of developing devices disposed along a movement direction of the photosensitive member, wherein a movement speed of the photosensitive member is lower when a selected developing device is the one closer to the station where the uniformly charging step is performed than when another developing device is selected, whereby the time periods for a portion of the photosensitive member to move from the charging station to the developing devices is substantially constant.
