PURPOSE:To enhance surface potential and to reduce residual potential by forming an amorphous silicon carbide photoconductive layer having 2 layer structure each layer region composed of a specified amount of specified element. CONSTITUTION:The amorphous silicon carbide photoconductive layer having the 2 layer structure forming a photosensitive layer on a conductive substrate together with an organic photosemiconductor layer is composed of a first layer region containing an element of group Va of the periodic table in a distribution increasing from the surface side of the photosensitive layer toward the substrate up to the maximum <=10,000ppm and a second layer region containing an element of group IIIa of the periodic table in an amount of 1-1,000ppm, thus permitting the obtained electrophotographic sensitive body to be enhanced in surface potential and low in residual potential. |
