PURPOSE:To enhance photosensitivity and surface potential and to reduce residual potential by forming a specified amorphous silicon carbide photoconductive layer composed of first, second, and third layer regions laminated successively. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating on a conductive substrate 1 the a-SiC photoconductive layer 2 composed of the 3 layer regions 2a, 2b, 2c laminated successively, and an organic semiconductor layer 3. The first layer region 2a and the third layer region 2c contain more C than the layer region 2b, and have each an atomic composition Si1-xCx, where 0.2<x<0.5, and the region 2a has a thickness of 0.01-1mum, and the region 2b has a thickness of 0.05-5mum, and the region 2c has a thickness of 10-2,000Angstrom , thus permitting all the characteristics of photosensitivity, residual potential resistance, and surface potential to be enhanced. |
