Abstract
An electrophotographic light-receiving member comprising a conductive support and provided thereon a photoconductive layer formed of a non-single-crystal material mainly composed of silicon atom and containing hydrogen atom and an element belonging to Group IIIb of the periodic table; wherein the photoconductive layer has hydrogen atom content, an optical band gap and a characteristic energy obtained from the exponential tail of light absorption spectra, all in specific ranges, and has on the surface side thereof a second layer region that absorbs a prescribed amount of light incident on the photoconductive layer and on the support side thereof the other first layer region; the element belonging to Group IIIb of the periodic table being contained in the second layer region in an amount made smaller than that in the first layer region. This can provide an electrophotographic light-receiving member that has achieved all the improvement in chargeability, the improvement in temperature characteristics thereof and the decrease in photomemory, and has been dramatically improved in image quality, and can provide an electrophotographic light-receiving member improved in temperature charact…
