Abstract
An electrophotographic lithographic printing plate precursor capable of well maintaining both the electrophotographic properties and the printing properties is provided, which comprises, at least, a photoconductive layer on one side of a support and an under layer directly under the photoconductive layer, in which the under layer consists of a plurality of layers comprising an outermost layer having a surface resistivity of at most 1.times.10.sup.11 .OMEGA. and an inner layer having a Cobb's water absorbing capacity of at most 15 g/m.sup.2 (45 minute value) or having a Young's Modulus of at most 1000 kg/cm.sup.2.
