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, at least one resin (A) which has a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and contains not less than 30% by weight of a polymer component of the formula (I) and from 0.5 to 15% by weight of a specified polar group-containing polymer component and at least one resin (B) which is an AB block copolymer having a weight average molecular weight of from 3.times.10.sup.4 to 1.times.10.sup.6 and comprising an A block containing a specified polar group-containing polymer component and a B block containing a polymer component of the formula (I). ##STR1## wherein a.sup.1 and a.sup.2 : 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.
