Photoconductive member of layer of A-Ge, A-Si increasing (O) and layer of A-Si(C) or (N)

摘要

A photoconductive member is provided which has a substrate for photoconductive member, and a light-receiving layer comprising (1) a first layer with a layer constitution in which a first layer region (G) comprising an amorphous material containing germanium atoms and a second layer region (S) exhibiting photoconductivity comprising an amorphous material containing silicon atoms are successively provided on said substrate from the aforesaid substrate side, and (2) a second layer comprising an amorphous material containing silicon atoms and at least one of carbon atoms and nitrogen atoms, said first layer having a layer region (O) containing oxygen atoms, wherein the depth profile of oxygen atoms in the layer thickness direction in said layer region (O) is increased smoothly and continuously toward the upper end surface of the first layer.
