Abstract
A light receiving member comprises a support and a light receiving layer having a photosensitive layer composed of a-Si(Ge,Sn)(H,X) or a-Si(Ge,Sn)(O,C,N)(H,X) and a surface layer composed of A-Si(O,C,N)(H,X), said support having a surface provided with irregularities composed of spherical dimples, each of which has an inside face provided with minute irregularities. The optical band gap possessed by the surface layer and the 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. In addition, the light-receiving member forms visible images of excellent quality even when coherent laser beams are used as the light source. The member also effectively prevents reflection of incident light at the interface between the surface layer and the photosensitive layer.
