Abstract

An electrophotographic photosensitive member, comprises an electroconductive support (1), optionally a charge blocking layer (2), a photoconductive layer (3,4) made from hydrogen-containing amorphous silicon as a matrix and a charge injection blocking layer (5). To give the member high electrostatic charge acceptance and a good photosensitivity, the charge injection blocking layer (5) has a different conductivity type from that of the photoconductive layer (3,4) and a broader optical band gap than that of the photoconductive layer (3,4). A moisture and corona-resistant layer (6) is also provided.
