ABSTRACT:
An electrophotographic lithographic printing plate, in which the effect by the hydrophilic property of non-image areas is further improved, and which is stable during storage even under very severe conditions and capable of readily realizing the hydrophilic property in a short time during processing of rendering hydrophilic is provided by a process for the production of an electrophotographic lithographic printing plate, comprising subjecting an electrophotographic photoreceptor to imagewise exposure and forming a toner image, the electrophotographic photoreceptor comprising an electroconductive support having provided thereon at least one photoconductive layer containing photoconductive inorganic compound and a binder resin, the binder resin comprising at least one resin (P) as defined herein, and optionally at least one crosslinking agent, and then subjecting a non-image area of the photoconductive layer to an oil-desensitizing processing with a processing solution containing a hydrophilic compound containing a substituent having a Pearson's nucleophilic constant n of at least 5.5.
