Abstract
This invention provides a processing method for exposed silver halide color photosensitive materials, which enables sufficient desilverization to be performed in a short time and highly photographic quality to be obtained. The processing method of this invention comprises the steps of: exposing silver halide color photosensitive material containing 5-pyrazolone-type or pyrazoloazole-type 2-equivalent magenta coupler to light; color developing said photosensitive material; and desilverizing said photosensitive material, wherein said desilverizing step uses a bleaching bath containing ferric complex salt aminopolycarboxylate, and thereafter uses a bleaching-and-fixing bath containing ferric complex salt aminopolycarboxylate.
