PROBLEM TO BE SOLVED: To attain an improvement in chargeability, an improvement in temperature characteristic and a reduction of optical memory and to upgrade image quality. SOLUTION: The electrophotographic photoreceptive member includes a photoconductive layer comprising a silicon-based non-monocrystalline material containing hydrogen and a group IIIb element of the periodic table on an electrically conductive support. The photoconductive layer is composed of a support side first layer region and a surface side second layer region each having a hydrogen content in a specified range, an optical bandgap in a specified range and a characteristic energy obtainable from an exponential function skirts of a light absorption spectra in a specified range, the optical bandgap of the second layer region is made smaller than that of the first layer region, and the content of the group IIIb element of the periodic table in the second layer region is made lower than that in the first layer region.
