In a processing method wherein, after a silver halide color photographic material is subjected to color development, the silver halide color photographic material is desilvered and then washed and/or stabilized, a photographic material that has at least one high-silver chloride emulsion layer, and in which at least one emulsion layer contains a monodisperse emulsion, is rapidly processed with a color developer having a water-soluble high polymer compound. The coating amount of silver of the said silver halide color photographic material is preferably 0.75 g/m or less, and the color developer contains chloride ions in an amount of 0.035 mol/liter or more. In continuous and rapid processing, fluctuations of photographic properties (particularly changes in sensitivity and gradation) are remarkably reduced, the ununiformity of developed density is remarkably improved, and the occurrence of a deposit on a processing tank wall surface is prevented.

Processing a silver halide color photographic material comprising color developing, desilvering and water washing and/or stabilizing. In this process, a photographic material which has at least one emulsion layer containing a high silver chloride content, and at least one emulsion layer containing a monodisperse emulsion, is continuously processed with a color developing solution containing a water-soluble high polymer compound.
