Light receiving members with spherically dimpled support

A light receiving member comprising (a) a support having an uneven-shaped surface of a plurality of spherical dimples, each of said spherical dimples having an identical radius of curvature R and an identical width D, wherein the ratio D/R of said width D to said radius of curvature R being from 0.03 to 0.07 and (b) a light receiving layer having a photosensitive layer and a surface layer having a free surface on said support;

• said photosensitive layer being composed of an amorphous material containing silicon atoms as the main constituent and, at least one kind selected from the group consisting of hydrogen atoms and halogen atoms;
• and said surface layer comprising a layer selected from the group consisting of (i) a layer composed of an amorphous material containing silicon atoms and at least one kind selected from the group consisting of oxygen atoms, carbon atoms and nitrogen atoms;
• (ii) a layer composed of an inorganic material containing one or more members selected from the group consisting of MgF.sub.2, Al.sub.2 O.sub.3, ZrO.sub.2, TiO.sub.2, ZnS, CeO.sub.2 CeF.sub.3, Ta.sub.2 O.sub.5 , AlF.sub.3 and NaF;
• and (iii) a multi-layered structure comprising an abrasion-resistant layer at the outermost side and a reflection preventive layer inside thereof.
