Electrophotographic light-sensitive material

U.S. Patent Number: 5382488

Abstract: An electrophotographic light-sensitive material which has improved electrostatic characteristics and image forming performance and is excellent particularly in reproducibility of highly accurate image using a liquid developer and image forming performance upon a scanning exposure system using a laser beam of a low power. The electrophotographic light-sensitive material contains, as a binder resin, a low molecular weight resin (A) comprising an organic molecule having bonded thereto at least three polymer chains each containing a polymer component of formula (I) and a polymer component having a specified polar group, and a resin (B) which is a medium to high molecular weight AB block copolymer comprising an A block containing a specified polar group and a B block containing a polymer component of formula (I). ##STR1## wherein a.sup.1 and a2: hydrogen, halogen, a cyano group, a hydrocarbon group, --COOR.sup.4 or --COOR.sup.4 bonded via a hydrocarbon group (R.sup.4 : hydrocarbon group); and R.sup.3 : a hydrocarbon group.
