Abstract
An electrophotographic photosensitive member comprises isolated conductive members forming picture elements, a photoconductive layer, transparent electrodes and color filter electrodes. Also, a color electrographic process which comprises applying voltage between a transparent electrode and color filter electrode of an electrophotographic photosensitive member comprising isolated conductive members forming picture elements, a photoconductive layer, transparent electrodes and color filter electrodes, conducting imagewise exposure from the side opposite to the side where the isolated conductive members are arranged, resulting in formation of difference in distribution voltage between the area that light passes through the color filter electrode and the area that light does not pass through the color filter electrode with regard to the voltage distribution between the transparent electrode and the isolated conductive member and between the color filter electrode and the isolated conductive member, thereby forming a voltage image depending upon the change of voltage of the isolated conductive member produced corresponding to the difference in the distribution voltage, and developing sa…
