Abstract
An electrophotographic printing plate precursor is disclosed, comprising a conductive support having provided thereo1 at least one photoconductive layer containing photoconductive zinc oxide and at least one resin binder, wherein said resin binder contains at least one functional group capable of forming at least one hydroxyl group and at least one carboxyl group upon decomposition. The printing plate precursor can reproduce an image faithful to an original and exhibits satisfactory surface smoothness and electrostatic characteristics. The printing plate produced from the precursor does not cause background stains and exhibits excellent printing durability.
