Abstract
An electrophotographic photosensitive member comprising a photoconductive layer formed over a substrate and a surface layer formed over the photoconductive layer and having a high photosensitivity and charge retaining ability at the surface layer, the photoconductive layer and the surface layer being composed chiefly of amorphous silicon, the surface layer being a layer containing carbon forming an insulating material as combined with the amorphous silicon, and the content of the carbon based on the silicon atoms being low toward the substrate and high toward the surface of the surface layer; which is usable for copying machines and intelligent copying machines.
