Abstract
A color electrophotographic process comprises applying voltage between a non-transparent electrode and a color filter electrode of an electrophotographic photosensitive member comprising isolated conductive members forming picture elements, a photoconductive layer, non-transparent electrodes and color filter electrodes, conducting imagewise exposure from the side where color filter electrodes are arranged, resulting in formation of a difference in distribution voltage between the area wherein light passes through the color filter electrode and the area wherein light does not pass through the color filter electrode with regard to the voltage distribution between the non-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 the voltage of the isolated conductive member caused corresponding to a difference in distribution voltage, and developing said voltage image with a color toner corresponding to a color light passing through the color filter electrode. Further there is disclosed an electrophotographic photosensitive member for a color electroph…
