ABSTRACT:
An improved photosensitive member for use in electrophotography which comprises a substrate and a light receiving layer having a charge carrier generation layer and a charge carrier transportation layer composed of a carbonic film the nucleus of which matrix being carbon atom, which contains 40 atomic % or less of hydrogen atom and which possesses an optical band gap of 1.5 eV or more and an electric 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.
