Organic photoreceptor and electrophotographic image forming apparatus including the organic photoreceptor

摘要

An organic photoreceptor and an electrophotographic image forming apparatus is provided including the organic photoreceptor, wherein the organic photoreceptor has the advantage of a conventional single-layered type photoreceptor and has higher photosensitivity and good repetition stability. The photoreceptor has a photosensitive layer on an electrically conductive substrate where the photosensitive layer has an electron transporting material that increases in concentration toward the interface between the substrate and the photosensitive layer.
