ABSTRACT:
A method for processing silver halide photosensitive materials is described which includes processing an imagewise-exposed silver halide photosensitive material in a bath which has a fixing ability and then at least one of washing and stabilizing the photosensitive materials in a multi-stage counter-flow system, wherein liquid from at least one of a water washing tank and a stabilizing tank is treated using a reverse osmosis membrane and the treated liquid is recycled to at least one of the water washing tank and the stabilizing tank, and at least a tank at the stage at which the liquid is removed for the reverse osmosis membrane treatment has an open fraction of not more than 0.03.
