Abstract
An improved photosensitive member for use in electrophotography which is characterized by having a substrate and a photoconductive layer comprising a carbonic film, the nucleus of which matrix being carbon atom, which contains 30 atomic % or less of hydrogen atom and at least one selected from the elements of Group III and Group V of the Periodic Table, and which has an optical band gap of more than 1.5 eV and an electrical conductivity of 10.sup.-11 .OMEGA..sup.-1 cm.sup.-1 or less. It is always and substantially stable regardless of the changes in use environments and it enables to make highly resolved images with a clear half-tone which are highly dense and quality at high speed.
