Abstract:
A method for processing silver halide photosensitive materials comprising developing an exposed silver halide photosensitive material, fixing the developed photosensitive material and then washing it with a washing water, the washing water used in the water washing process being replenished in an amount of 2 to 50 times the volume of liquid carried over by the photosensitive material from a bath preceding the water washing bath per unit area thereof, the amount of calcium and magnesium compounds present in the water washing bath being reduced to not more than 5 mg/l, respectively, on the basis of elemental calcium and magnesium and the washing water containing at least one chelating agent having a stability constant of a chelate, which is formed between the chelating agent and calcium or magnesium, of at least 6 is herein disclosed. The method makes it possible to suppress the increase in turbidity due to the proliferation of bacteria and molds in washing bath even when the processing is continuously conducted while substantially saving the amount of washing water and further provides an excellent processed photosensitive materials.
