Abstract
Disclosed is an electrophotographic process comprises applying voltage between a transparent electrode and an opaque electrode of a photosensitive member comprising isolated electrically conductive members forming image elements, a photoconductive layer, transparent electrodes and opaque electrodes, imagewise exposing the side opposite the side where the isolated electrically conductive members are arranged, resulting in formation of voltage differences between the area where light passes through a transparent electrode and the area where light does not pass through the transparent electrode, said distribution voltage being a voltage between the transparent electrode and the isolated electrically conductive electrode and a voltage between the opaque electrode and the isolated electrically conductive electrode, thereby forming a voltage image depending upon the change of voltage of the isolated electrically conductive member produced corresponding to the difference in the distribution voltage, and scanning the electrophotographic photosensitive member within the area where imagewise exposure is carried out, or moving an image receiving member and an optical image projected on the el…
