Member having light receiving layer with nonparallel interfaces
 A light-receiving member comprises a substrate for light-receiving member and a light-receiving layer of a multi-layer structure having a first layer comprising an amorphous material containing silicon atoms and germanium atoms, a second layer comprising an amorphous material containing silicon atoms and exhibiting a photoconductivity, and a surface layer comprising an amorphous material containing silicon atoms and carbon atoms provided on the substrate successively from the substrate side, said light-receiving layer having at least one pair of nonparallel interfaces within a short range and said nonparallel interfaces being arranged in a large number in at least one direction within the plane perpendicular to the layer thickness direction.
