PURPOSE:To restrain rise of potential in the light and fluctuation of potential in the dark even at the time of repeated uses, and to obtain an electrophotographic sensitive body capable of forming a stable image by forming an undercoat contg. a polymer compd. having viologen structures on a substrate and laminating a photosensitive layer on it. CONSTITUTION:The undercoat is formed by coating the conductive substrate with a dimethylformamide soln. of a polymer compd. obtained by reacting viologen, that is, 1,1'-dialkyl-4,4'-bipyridinium with an acrylonitrile- chloromethylstyrene copolymer, and drying it, and a photoconductive layer is formed by successively laminating an electrostatic charge generating layer and a charge transfer layer on the undercoat, thus permitting the undercoat to be given functions as adhesive and barrier layers, and consequently, the obtained photosensitive layer to easily carry electrons generated in the photoconductive layer even under low temp. and low humidity to the side of the substrate and to form a stable image suitable for use in laser printers and the like without rise of potential in the light. |
