Abstract
A light-receiving member comprises a substrate having a large number of protruding portions on a surface thereof, each of said protruding portions having at a predetermined cut position a sectional shape comprising a main projection and a subprojection, the main projection and the subprojection overlapping each other, and a light-receiving layer with a multi-layer structure having a first layer comprising an amorphous material containing silicon atoms and germanium atoms, a second layer comprising an amorphous material containing silicon atoms and exhibiting photoconductivity, and a surface layer having the reflection preventive function provided successively from the substrate side, said light-receiving layer containing at least one selected from oxygen atoms, carbon atoms and nitrogen atoms.
