ABSTRACT:
There is provided a light receiving member which comprises a support, a photosensitive layer and a surface layer, said photosensitive layer being composed of amorphous material containing silicon atoms, and at least either germanium atoms or tin atoms and said surface layer being composed of amorphous material containing silicon atoms and at least one kind selected from oxygen atoms, carbon atoms and nitrogen atoms, said support having a surface provided with irregularities composed of spherical dimples, and an optical band gap being matched at the interface between said photosensitive layer and said surface layer. The light receiving member overcomes all of the problems in the conventional light receiving member comprising a light receiving layer composed of an amorphous silicon and, in particular, effectively prevents the occurrence of interference fringe in the formed images due to the interference phenomenon thereby forming visible images of excellent quality even in the case of using coherent laser beams possible producing interference as a light source.
