PURPOSE:To improve flatness and strength, electrostatic characteristics, image pick-up characteristic of a photoconductive layer, to prevent a printed matter from ground stain, and to improve durability of an electrophotographic sensitive body for repeated printing by incorporating at least two kinds of resin into a binder resin. CONSTITUTION:A binder resin contains at least one kind of a resin A and at least one kind of a resin B. Said resin A has 1X10<3>-1X10<4> weight average molecular weight and contains 0.05-15mol.% copolymer component having at least one kind of acidic groups selected from a group expressed by formula I, -PO3H2 group, -SO3H group, and -COOH group. Said resin B is a thermosetting resin contg. crosslinking functional groups. In formula I, R is a hydrocarbon group. Thus, the flatness, mechanical strength, electrostatic characteristics, image pick-up characteristic of the photoconductive layer are improved, printed matters are prevented from ground stain and the durability of the electrophotographic sensitive body for repeated printing is improved. |
