ABSTRACT:
An electrophotographic lithographic printing plate precursor having a photoconductive layer containing resin (A) having a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4 and containing a polymer component of the specified repeating unit and a polymer component having a polar group and dispersed resin grain (L) which is obtained by dispersion polymerization of monomer (C) containing a functional group capable of forming at least one group selected from a thiol group, a sulfo group, an amino group and a ##STR1## group upon decomposition in the presence of a dispersion stabilizing resin soluble in a non-aqueous solvent and which has a silicon and/or fluorine atom-containing substituent.
The electrophotographic lithographic printing plate precursor has good electrophotographic characteristics and water retentivity due to the suitable interaction between zinc oxide, a spectral sensitizing dye, the resin (A) and the dispersed resin grain (L).
