ABSTRACT:
An electrophotographic lithographic printing plate precursor which is suitable for not only the ordinary developing methods but also the developing methods of direct electron injection system and which after developing, can readily be wound and fixed, as a lithographic printing plate, around a drum of a printing machine without any slippage after winding is provided. This precursor comprise a base of paper coated, on both surfaces thereof, with .alpha.-polyolefin laminated layers each having a volume resistivity of at most 1.times.10.sup.10 .OMEGA. and being further provided, on one side thereof, with a photoconductive layer and on the other side thereof, with an over back layer having a surface resistivity of at most 1.times.10.sup.10 .OMEGA. and a larger friction coefficient than the .alpha.-polyolefin laminated layer.
