  • the aperture areas in the processing machine described above were 120 cm 2 in the color developing solution, 120 cm 2 in the bleaching solution, and 100 cm 2 in the other processing solutions.
  • compositions of the processing solutions are shown below:
  • the residual silver amount at the maximum density part was measured in the same manner as that in Example 1 to find that it was 4.0 mg/cm 2 and a desilvering performance was good.
  • the metal chelate compound of the present invention in the embodiment of the present invention is a compound having a biodegradability and contributes to an environmental protection.
  • the processing composition of the present invention using it enables a rapid processing providing an excellent desilvering performance and has less fluctuation in a processing performance before and after running.
