PURPOSE:To enhance electrophotographic characteristics, especially, photosen- sitivity, and durability by incorporating an electron receptor in a surface coating layer in an amount of 0.1-0.5wt.%. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating on a conductive substrate 1 a photosensitive layer 4a comprising an electric charge generating layer 2 and a charge transfer layer 3 in this order or in the reverse order in the case of the photosensitive layer 4b, and the surface coating layer 5 containing the electron receptor in an amount of 0.1-5.0wt.%, thus permitting charge generated at the time of exposure to the photosensitive body to rapidly reach the surface of the photosensitive body without being hindered by the layer 5, and the distinguish the surface charge, and consequently, the obtained surface coating layer to be superior in durability and the obtained photosensitive body to be high in sensitivity and low in residual potential. |
