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, each dimple having an identical radius of curvature R and an identical width D, wherein the ratio 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 an outer layer which formed from an amorphous material containing silicon atoms as the main constituent and at least one of hydrogen atoms and halogen atoms. The light receiving layer contains an inner layer of amorphous silicon which also contains germanium and/or tin and hydrogen and/or halogen. 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.
