ABSTRACT:
An electrophotographic light-sensitive material having a photoconductive layer containing at least an inorganic photoconductive substance and a binder resin, wherein the binder resin comprises (A) at least one AB block copolymer (Resin (A)) having a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and composed of an A block comprising at least one polymer component containing at least one acidic group as described herein, and a B block containing at least a polymer component represented by formula (I) described herein, wherein the content of the polymer containing the acidic group in the AB block copolymer is from 0.5 to 20 parts by weight per 100 parts by weight of the AB block copolymer; and (B) at least one copolymer (Resin (B)) having a weight average molecular weight of not less than 3.times.10.sup.4 and formed from at least a monofunctional macromonomer (MB) described herein having a weight average molecular weight of not more than 2.times.10.sup.4 and a monomer represented by general formula (V) described herein.
