ABSTRACT:
This is provided an improved light receiving member having at least a photoconductive layer constituted with A-Si(H,X) series material and a surface layer constituted with A-Si(C,O,N)(H,X) for use in electrophotography, etc. which is characterized in that the atom(C,O,N) is contained in the surface layer in a state that the concentration of the atom(C,O,N) is grown increasingly starting from the position of the interface between the surface layer and the photoconductive layer while leaving a portion corresponding to a refractive index difference (.DELTA.n) [.DELTA.n.ltoreq.0.62] between the refractive index of the surface layer and that of the photoconductive layer which can be disregarded in the image-making process toward the free surface of the surface layer.
