IMAGE FORMING METHOD AND METHOD FOR PRODUCING PLANOGRAPHIC PRINTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a new image forming method by which the deposition efficiency of silver and the adhesiveness of image silver are enhanced and to provide a method for producing a planographic printing plate having improved printing resistance and improved lipophilic property (ink receptivity) of image silver. SOLUTION: In the image forming method, a photosensitive material with a silver halide emulsion layer on an aluminum plate with an alumite layer is exposed and electric current is supplied to the photosensitive material in an alkali processing solution in the presence of a developing agent and a solvent for silver halide.
