Electrophotographic lithographic printing plate precursor

An electrophotographic lithographic printing plate precursor which utilizes an electrophotographic light-sensitive material comprising a conductive support having provided thereon at least one photoconductive layer containing photoconductive zinc oxide and a binder resin, wherein the binder resin contains at least one graft-type copolymer formed from, as a polymerizable component, at least one monofunctional macromonomer which has a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4, comprises at least one polymer component containing a functional group which has at least one atom selected from a fluorine atom and a silicon atom and is capable of forming at least one hydrophilic group selected from a sulfo group, a phosphono group, a carboxy group and a hydroxy group through decomposition, and has a polymerizable double bond group represented by the general formula (I) described below bonded to only one terminal of the main chain thereof ##STR85## wherein X.sub.1 represents --COO--, --OCO--, (CH.sub.2).sub.n OCO--, (CH.sub.2).sub.m COO--, --O--, --SO.sub.2 --, --CO--, --CONHCOO--, --CONHCONH--, ##STR86## (wherein d.sub.1 represents a hydrogen atom or a hydrocarbon group;

• and n and m each represents an integer of from 1 to 4);
• and a.sub.1 and a.sub.22, which may be the same or different, each represents a hydrogen atom, a halogen atom, a cyano group, a hydrocarbon group, --COO--Z.sub.1 or --COO--Z.sub.1 bonded via a hydrocarbon group (wherein Z.sub.1 represents a hydrocarbon group which may be substituted), and at least one monomer copolymerizable with the monofunctional macromonomer, and the content of the monofunctional macromonomer is from 5 to 70% by weight in the graft type copolymer.
