PURPOSE:To improve the electrostatic charge characteristic of an electrophotographic sensitive body having an amorphous photoconductive layer consisting essentially of silicon and/or germanium on a conductive substrate by providing an insulating amorphous silicon oxide (a-SiOx) layer between the substrate and the photoconductive layer. CONSTITUTION:The insulating amorphous silicon oxide (a-SiOx) layer is provided on the substrate, then the photoconductive layer contg. the amorphous silicon and or amorphous germanium is formed on said a-SiOx layer by glow discharge decomposition onto the substrate. The electrophotographic sensitive body obtd. in the above-mentioned manner has such characteristics as high electrostatic charging power (surface potential in the stage of corona charge), small dark attenuation, stabilized repetitive charge characteristics, the freedom of the exfoliation of the amorphous photoconductive layer from the substrate and the absence of the residual potential. |
