Abstract

The invention relates to an electrophotographic member which is highly sensitive to the light of long wavelengths. Amorphous silicon is used as a photosensitive base member. A long wavelength sensitizing region has a narrower forbidden band gap width than that of the base member, and consists of at least two semiconductor films that are laminated and that have at least different forbidden band gap widths or different conductivities. An increased number of semiconductor films may, of course, be laminated to constitute the sensitizing region.
