ABSTRACT:
An electrophotographic light-sensitive material comprising a support having provided thereon a photoconductive layer containing an inorganic photoconductive substance and a binder resin, wherein the binder resin contains at least one graft type copolymer containing, as a copolymerizable component, at least one monofunctional macromonomer (M) having a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and comprising an AB block copolymer being composed of an A block comprising at least one polymerizable component containing at least one acidic group selected from --PO.sub.3 H.sub.2, --COOH, --SO.sub.3 H, a phenolic hydroxyl group, ##STR1## (wherein R represents a hydrocarbon group or --OR' (where R' represents a hydrocarbon group)) and a cyclic acid anhydride-containing group, and a B block containing at least one polymerizable component represented by general formula (I) and having a polymerizable double bond group bonded to the terminal of the main chain of the B block polymer ##STR2## wherein a.sub.1 and a.sub.2 each represents a hydrogen atom, a halogen atoms, a cyano group, a hydrocarbon group, --COOZ.sub.2 or --COOZ.sub.2 bonded via a hydrocarbon group (wherein Z.sub.2 represents a hydrogen atom or a hydrocarbon group); V.sub.1 represents --COO--, --OCO--, --CH.sub.2).sub.l1 OCO--, --CH.sub.2).sub.l2 COO-- (wherein l.sub.1 and l.sub.2 each represents an integer of from 1 to 3), --O--, --SO.sub.2 --, --CO--, ##STR3## (wherein Z.sub.1 represent a hydrogen atom or a hydrocarbon group), --CONHCOO--, --CONHCONH--, or ##STR4## and R.sub.1 represents a hydrocarbon group, provided that when V.sub.1 represents ##STR5## R.sub.1 represents a hydrogen atom or a hydrocarbon group.
