Electrophotographic light receiving members comprising amorphous silicon
and substrate having minute irregularities
摘要:
A light receiving member comprises a support and a light receiving layer of a multi-layered structure having at least a photosensitive layer composed of an amorphous silicon, said support having a surface provided with irregularities composed of spherical dimples each of which having an inside face provided with minute irregularities. The light receiving layer may contain a surface layer comprising an outer abrasion-resistant layer and an inner reflection prevention layer, wherein the optical band gap possessed by the surface layer and optical band gap possessed by the photosensitive layer on which the surface layer is disposed are matched at their interface. The light receiving member can effectively prevent the occurrence of interference fringes in the formed images, forming visible images of excellent quality even when coherent laser beams are used as the light source. The member can also effectively prevent reflection of incident light at the interface between the surface layer and the photosensitive layer.
