ABSTRACT:
Silver halide photosensitive material after exposure is processed by developing it with a developer solution and then processing it with a processing solution having bleaching function and/or a processing solution having fixing function, while placing the developer solution and/or said processing solution having fixing function in contact with the other processing solution and/or an electrolyte solution through an anion exchange membrane, placing a cathode in the developer solution and/or the processing solution having fixing function and an anode in the other processing solution and/or the electrolyte solution, and conducting electricity therebetween. An alternative method involves placing the processing solution having bleaching function in contact with the other processing solution and/or an electrolyte solution through an anion exchange membrane, placing an anode in the processing solution having bleaching function and a cathode in the other processing solution and/or the electrolyte solution, and conducting electricity therebetween. The respective processing solutions maintain constant processing ability.
