Abstract
An electrophotographic photosensitive member is disclosed which has an electroconductive support and a photosensitive layer formed thereon. The photosensitive member is electrified by applying voltage to an electrification means brought into contact therewith, and it has higher impedance (.OMEGA..cndot.cm) at an end portion than at other portion of the area where the photosensitive member is allowed to contact with the electrification means. Also, a process cartridge and an electrophotographic apparatus using the photosensitive member are disclosed.
