Multilayer photoreceptor

摘要

Disclosed is a photoreceptor which comprises a charge generation layer composed of at least one compound selected from the group consisting of amorphous hydrogenated silicon, amorphous fluorinated silicon and amorphous hydrofluorinated silicon, a charge transport layer formed on a lower surface of said charge generation layer and composed of at least one compound selected from the group consisting of amorphous hydrogenated silicon nitride, amorphous fluorinated silicon nitride, amorphous hydrofluorinated silicon nitride, amorphous hydrogenated silicon carbide, amorphous fluorinated silicon carbide and amorphous hydrofluorinated silicon carbide, and a substrate, wherein said charge transport layer contains oxygen within the range of from 50 atomic ppm to 5 atomic % based on the total atoms of silicon, nitrogen and carbon. The photoreceptor of this invention can be improved in the electrophotographic characteristics greatly with reduction of dependency on temperature by making the oxygen content in the charge transport layer 50 atomic ppm to 5 atomic %.
