Abstract
A method for preparation of an electrophotographic printing plate which can provide a printing plate excellent in image qualities of plate-making and printing, and continuously produce such printing plates in a stable manner for a long period of time and which is suitable for a scanning exposure system using a laser beam. The method comprises forming a toner image by an electrophotographic process on a peelable transfer layer of an electrophotographic light-sensitive material which comprises an electrophotographic light-sensitive element a surface of which has releasability and the peelable transfer layer provided on the surface thereof which contains a thermoplastic resin capable of being removed upon a chemical reaction treatment, thermally transferring the toner image together with the transfer layer onto a support for a lithographic printing plate and removing the thermoplastic resin upon a treatment, for example, with an aqueous alkaline solution, whereby a printing plate is obtained.
