    摘要： An electrophotographic light-sensitive material is described. The material is comprised of an electrically conductive support and a light-sensitive layer on the support. The light-sensitive layer contains a copolymer comprising: (a) vinylidene chloride or vinyl chloride; (b) a vinyl based unsaturated monomer represented by the general formula: CH.sub.2 =C(R.sub.1)(R.sub.2) (wherein the symbols are as defined in the appended claims); and (c) a vinyl monomer containing a hydroxyl group at the side chain thereof. This light-sensitive layer exhibits good adhesive properties, is superior in durability and moisture resistance, and produces images free from white spots and fog.
