PURPOSE:To improve the electrifying characteristic such as sensitivity, durability and moisture resistance, etc. by providing a conductive layer, electric charge generating layer and charge transfer layer contg. >=1 kinds among the hydrazone compds. expressed by the specific formula on a substrate. CONSTITUTION:A conductive layer is provided on a substrate and a charge generating layer consisting of an inorg. material such as selenium, an org. material such as a dye, pigment, etc. or other materials is laminated thereon via an adhesive agent layer consisting of casein, PVA, etc. The solvent soln. of the hydrazone compd. expressed by the formula (R1, R2 denote an alkyl group, aralkyl group, aryl group, R3, R4 denote a hydrogen atom, alkyl group, aralkyl group, aryl group, R5, R6 denote a hydrogen atom, alkyl group of 1-4 carbon atoms, respectively) is coated on the charge generating layer to laminate the charge transfer layer, by which the electrophotographic sensitive body is obtd. |
