Electrophotographic light-sensitive material

摘要

An electrophotographic light-sensitive material comprising a support having provided thereon at least one photoconductive layer containing an inorganic photoconductive substance and a binder resin, wherein the binder resin comprises at least (A) a low-molecular weight resin (resin A) of a graft copolymer formed from at least a monofunctional macromonomer (MA) and a monomer represented by the general formula (III) (monomer A), and having a specific acidic group bonded to only one terminal of the polymer main chain, and (B) a high-molecular weight resin (resin B) of a graft copolymer formed from at least one polyester type macromonomer (MB) represented by general formula (VIa), (VIb), (VIc) and (VId), wherein all the formulas are as defined in the specification. In a preferred embodiment the high-molecular weight resin (B) has at least one acidic group at the terminal of the main chain of the polymer. The electrophotographic light-sensitive material exhibits excellent electrostatic characteristics and mechanical strength even under severe conditions, and is advantageously employed in a scanning exposure system using a semiconductor laser beam.
