Abstract
There is provided a light receiving member which comprises a support and a light receiving layer having a photosensitive layer composed of amorphous material containing silicon atoms and at least either germanium atoms or tin atoms and a surface layer, said surface layer being of multi-layered structure having at least an abrasion-resistant layer at the outermost side and a reflection preventive layer in the inside, and said support having a surface provided with irregularities composed of spherical dimples. 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.
