Abstract
Abstract In a method of processing a light-sensitive silver halide photographic material by processing the light-sensitive silver halide photographic material with a processing solution having fixing ability and subsequently processing it with a water washing-substitutive stabilizing solution substantially without carrying out water washing, the improvement wherein the concentration of a sulfite in said water washing-substitutive stabilizing solution is controlled to be 1.0×10 -5 mole/liter or more when the concentration of silver compounds in said water washing-substitutive stabilizing solution is from 1/2 to 1/1000-fold of the concentration of silver compounds in the preceding bath. According to the method of this invention, generation of sulfiding and mold or bacteria can be prevented, whereby dye images without drop out portion can be obtained.
