Electrophotographic light-receiving member having surface region with high ratio of Si bonded to C

摘要

An electrophotographic light-receiving member comprises a substrate, a photoconductive layer formed on the substrate and composed of a non-single crystal material containing a base component silicon atoms and a surface layer (surface-side region) made of a non-single crystal material containing silicon, carbon and hydrogen atoms, in which the ratio of silicon atoms having at least one bond to a carbon atom in the surface layer is at least 50% of the total number of silicon atoms. The electrophotographic light-receiving member has good initial electrophotographic properties and particularly good durability under a high-humidity environment.
