PURPOSE:To enhance electrophotographic characteristics and printing resistance by forming a surface protective layer made of organosilanol and polymethyl methacrylate on an organic photosensitive layer. CONSTITUTION:The electrophotographic sensitive body is obtained by successively laminating on a conductive substrate 1 the organic photosensitive layer 5 composed of an electric charge transfer layer 3 and a charge generating layer 2, and the surface protective layer 4 made of the organosilanol and the polymethyl methacrylate good in wettability with the binder resin to be used for the layers 2, 3, and it is high in electric resistance at low temperature and causes deterioration of sensitivity and background stains, but it can be lowered in the resistance to a desired value with the specified amount of organosilanol low in electric resistance, and this resin is small in water adsorptivity and can prevent image trailing. |
