Abstract

A method for processing a silver halide color photographic light-sensitive material is disclosed. Fogging caused by the color developer contaminated by heavy metal ions is surpressed by the processing method. The processing method is excellent in the point that stable photographic propertied can be obtained for long while of running. The processing method comprises a step for developing with a color developer an imagewise exposed light-sensitive material which comprises a support and a photographic layer being provided on the support and including at least one silver halide emulsion layer, wherein the photographic layer has a swelling ratio within the range of from 1.5 to 3.5 and the silver halide emulsion layer comprises a silver halide emulsion having a silver chloride content of not less than 90 mole %, and the developing step is performed for a time of not less than 90 seconds with a color developer containing a compound represented by the following Formula (1): ##STR1## wherein R.sub.1 and R.sub.2 are each a hydrogen atom or an alkyl group provided that R.sub.1 and R.sub.2 are not hydrogen atoms at the same time, and R.sub.1 and R.sub.2 may be combined to form a ring.
