PURPOSE:To enhance image characteristics and durability by forming 2 photosensitive layers composed of a lower Se-As alloy layer, and an upper halogen-doped Se-As alloy layer of 1-5mum thickness, and an interlayer composed of an a-Si (amorphous silicon) layer substantially transparent in the visible light region. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating on a conductive supporting body 1 the 2 photosensitive layers composed of the lower Se-As alloy layer 2, and the upper halogen-doped Se-As alloy layer 3 of 1-5mum thickness, and the interlayer 4 made of an a-Si substantially transparent in the visible light region, and a surface protective layer 5, thus permitting image characteristics to be improved, always stable shape hard copies to be obtained, and long period stability to be enhanced. |
