Method for preparation of printing plate by electrophotographic process and apparatus for use therein

Abstract

A method for preparation of a printing plate by an electrophotographic process comprising providing a peelable transfer layer mainly containing a resin (A) capable of being removed upon a chemical reaction treatment on an electrophotographic light-sensitive element, forming a toner image on the transfer layer by an electrophotographic process, transferring the toner image together with the transfer layer onto a primary receptor, transferring the toner image together with the transfer layer from the primary receptor onto a receiving material having a surface capable of providing a hydrophilic surface suitable for lithographic printing at the time of printing, and removing the transfer layer on the receiving material in a non-image area by the chemical reaction treatment.
