Abstract
An electrophotographic light-receiving member has a surface layer of a non-single crystal material (Si.sub.x C.sub.y O.sub.z).sub.t H.sub.u F.sub.v (wherein 0.1.ltoreq.x.ltoreq.0.4, 0.4.ltoreq.y.ltoreq.0.7, 0.05.ltoreq.z.ltoreq.0.2, x+y+z=1, 0.299.ltoreq.t.ltoreq.0.589, 0.41.ltoreq.u.ltoreq.0.7, 0.001.ltoreq.v.ltoreq.0.1 and t+u+v=1), in which the ratio of silicon atoms bonded to carbon atoms in the surface layer is at least 50% of the total number of silicon atoms, and the ratio of silicon atoms bonded to oxygen atoms is 10 to 30 atomic % of the total number of silicon atoms.
