ABSTRACT:
A process for producing an electrophotographic light-sensitive material comprising a support having provided thereon a photoconductive layer containing an inorganic photoconductive substance and a binder resin is disclosed. The method comprises mixing the inorganic photoconductive substance and the binder resin to prepare a dispersion for forming the photoconductive layer, and coating the dispersion on the support, wherein the binder resin contains at least one resin (A) which has a weight average molecular weight of from 1.times.10.sup.3 to 1.times.10.sup.4 contains a repeating unit represented by the formula (I) specified above as a polymer component, has a crosslinked structure prior to the preparation of the dispersion for forming the photoconductive layer, and has at least one acidic group bonded at only one terminal of at least one polymer main chain. The electrophotographic light-sensitive material obtained according to the present invention is excellent in electrostatic characteristics and anti-humidity.
