PURPOSE:To obtain an electrophotographic sensitive body capable of holding stably superior electrostatic characteristics against variation of environmental conditions in the stage of forming reproduced picture images by incorporating two kinds of specified resin into a binder resin constituting a photoconductive layer. CONSTITUTION:In an electrophotographic sensitive body produced from an inorganic photoconductive material, binder resin, etc., the binder resin contains at least one kind of resin A and at least one kind of resin B. The resin A is a polymer having 1X10<3>-2X10<4> weight average mol.wt., contg. also >=30wt.% at least one kind of recurrent unit expressed by the formula I or II, wherein at least one kind of substituent selected from -PO3H2 group, -SO3H group, -COOH group, etc., is bonded to only one terminal of the principal chain of the polymer. The resin B is a copolymer resin consisting of a monofunctional macromonomer having <=2X10<4> weight average mol.wt. having specified polymerizable double bonds bonded thereto and a specified monomer. |
