US 2005/0238976 A1 · Electrophotographic photosensitive member

Abstract

There is provided an electrophotographic photosensitive member used in an electrophotographic apparatus which meets energy saving and higher image quality. The electrophotographic photosensitive member has excellent potential properties, and can suppress the image quality degradation caused by interference. The electrophotographic photosensitive member of the present invention including on a conductive substrate at least a photoconductive layer mainly composed of amorphous silicon, a surface layer, and at least one intermediate layer interposed between the photoconductive layer and the surface layer, wherein the surface layer contains a metal fluoride (exclusive of silicon fluoride) and the intermediate layer contains a metal oxide.
