ABSTRACT:
An electrophotographic lithographic printing plate precursor comprising a conductive support having provided thereon at least one photoconductive layer and further provided thereon an outermost surface layer is disclosed, in which said surface layer contains at least one resin having at least one functional group capable of forming a carboxyl group upon decomposition which is represented by formula (I): ##STR1## wherein x is as defined in the specification. The surface layer can be rendered highly hydrophilic while exhibiting water resistance when subjected to oil-desensitization processing after toner image formation to provide a lithographic printing plate having excellent printing durability.
