Abstract: This invention provides a processing method for an exposed silver halide color photographic material, which enables cut-down of the times required for bleaching-and-fixing and for washing and yet affords a stable image excellent in color reproduction. The processing method of this invention is characterized in that the silver halide color photographic material is developed with a color developing solution substantially free of benzyl alcohol, and that the thus developed photographic material is subjected to bleaching-and-fixing for a time of not more than 70 seconds and then subjected to washing for a time of not more than 70 seconds. Another important aspect of the invention resides in the use of a magenta coupler in the processing method with a merit that a stable colored image having excellent hue is developed without the fear of formation of stains although the times for the bleaching-and-fixing and for the washing are shortened remarkedly.
