ABSTRACT:
An electrophotographic light-sensitive material comprising a support having provided thereon a photoconductive layer containing at least an inorganic photoconductive substance, a spectral sensitizer and a binder resin, wherein the binder resin contains (1) at least one resin (Resin (A)) having a weight average molecular weight of from 1.times.10.sup.3 to 1.times.10.sup.4 which contains at least 30% by weight of a polymer component represented by the general formula (I) described below and from 0.1 to 10% by weight of a polymer component containing at least one acidic group selected from ##STR1## (wherein R represents a hydrocarbon group or --OR' (wherein R' represents a hydrocarbon group) and a cyclic acid anhydride-containing group, and (2) at least one resin (Resin (B)) having a weight average molecular weight of 5.times.10.sup.4 or more, containing a recurring unit represented by the general formula (III) described below as a copolymer component, and having a crosslinked structure made before the preparation of a dispersion for forming the photoconductive layer: ##STR2##
