Abstract
For providing a light receiving member for electrophotography improved in chargeability, temperature characteristic of sensitivity, and optical memory characteristic and presenting excellent quality of image, the light receiving member for electrophotography comprises an electrically conductive substrate and a photoconductive layer of a non-monocrystal material containing hydrogen atoms in the matrix of silicon atoms, wherein the photoconductive layer has regions formed under such conditions as to obtain a first layer region and a second layer region both having characteristic energy (Eu) of not more than 55 meV obtained from a linear portion (an exponential tail) of a function expressed by Equation (I) defined below with photon energy (h.nu.) as an independent variable and absorption coefficient (.alpha.) of photoabsorption spectrum as a dependent variable:
