Member with light receiving layer of A-SI(GE) and A-SI and having plurality of non-parallel interfaces
 A light receiving member comprises 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 photoconductivity and a surface layer having reflection preventive function provided on a substrate successively from the substrate side, said light receiving layer having at least one pair of non-parallel interfaces within a short range and said non-parallel interfaces being arranged in a large number in at least one direction within the plane perpendicular to the layer thickness direction.
