摘要： Photographic silver halide photosensitive material is processed, after exposure, by treating it with a working fixer solution. The photosensitive material comprises at least one layer of silver halide emulsion on a support and contains at least 10% by weight, based on gelatins, of a gelatin having an isoelectric point of at least 5.0 on the emulsion layer side. The working fixer solution is prepared by furnishing a fixer concentrate of at least pH 5 containing a thiosulfate as a fixing agent, 0.05-0.8 mol/liter of a sulfite and up to 0.01 mol/liter of a water-soluble aluminum salt, and diluting the fixer concentrate with water, thereby forming the working fixer solution containing a minimized amount of ammonium thiosulfate and 0.5-2.5 mol/liter of sodium thiosulfate. The method provides improved rapid processing with increased degrees of fixation and drying while preventing the generation of sulfurous acid and ammonia gases.
