ABSTRACT:
A light receiving member has a support and a light receiving layer. The support has an uneven-shaped surface of a plurality of spherical dimples formed by the impact of a plurality of rigid true spheres on the surface of the support. Each of the dimples has an identical radius of curvature R and an identical width D, wherein the radio D/R of the width D to the radius of curvature R is from 0.03 to 0.07. The light receiving layer is a multi-layered structure having a free surface which formed from an amorphous material containing silicon atoms as the main constituent, at least one of oxygen atoms, carbon atoms and nitrogen atoms, and at least one of hydrogen atoms and halogen atoms. The light receiving layer contains a layer region which functions as a photosensitive layer.
The light receiving member, when used with a coherent laser beam as an optical source, acts to prevent the occurrence of an interference fringe pattern during image formation. Further, the light receiving member has a high photosensitivity in the entire visible light region; is photosensitive to longer wavelengths; exhibits a rapid optical response; shows better electrical, optical and electroconductive properties; resists electrical voltage breakdown and is resistant to the effects of harsh environments.
