Electrophotographic light-sensitive material
摘要:
An electrophotographic light-sensitive material comprising a support having provided thereon a photoconductive layer containing at least an inorganic photoconductive substance and a binder resin, wherein the binder resin comprises (1) at least one graft type copolymer (Resin (A)) having a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and containing, as a copolymerizable component, at least one mono-functional macromonomer (M) 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' (wherein R' represents a hydrocarbon group)) and a cyclic acid anhydride-containing group, and a B block containing at least one polymerizable component represented by the general formula (I) and having a polymerizable double bond group bonded to the terminal of the main chain of the B block polymer ##STR2## and (2) at least one resin (Resin (B)) having a weight average molecular weight of 5.times.10.sup.4 or more, containing a repeating unit represented by the general formula (III) as a copolymerizable component, and having a crosslinked structure made before the preparation of a dispersion for forming the photoconductive layer ##STR3##
