ABSTRACT:
A photosensitive member for electrophotography comprises a first and a second photoconductive layer sequentially formed on a conductive layer. The first photoconductive layer has a spectral sensitivity extending over a range of light rays from ultraviolet rays to visible light. The second photoconductive layer is of light transmissibility, which is formed with a single or a compound layer and has a filtering action to transmit only light of longer wavelengths than a given one so as to define a range of light incident upon the first photoconductive layer, and a spectral sensitivity only to rays of shorter wavelengths than the given one.
