Abstract
In a method of processing an image-wise exposed silver halide color photographic material by applying thereto at least a color development processing and a silver removal processing (including performing a bleaching and a fixing separately or simultaneously, (e.g., a blixing)), the improvement which comprises processing, after the color development processing, the silver halide color photographic material with a processing bath containing a compound, as a bleach accelerator, represented by the following general formula (I): ##STR1## wherein R represents an --NR.sup.4 R.sup.5 group, an --O--R.sup.6 group or an --S--R.sup.6 group; R.sup.6 represents an atomic group necessary for forming a ring together with R.sup.1 ; R.sup.1, R.sup.4 and R.sup.5, which may be the same or different, each represents a hydrogen atom or an alkyl group; R.sup.2 and R.sup.3, which may be the same or different, each represents a hydrogen atom or a methyl group; n represents 1 or 2; X represents an amino group, a hydroxyl group, a --COO(M).sub.m group or an --SO.sub.3 (M).sub.m group; M represents a cation rendering the compound water soluble; and m represents 0 or 1 and is 0 when the compound forms an inner salt; the nitrogen atom bound to R.sup.1 may be quaternized with the charge of the quaternized nitrogen atom being neutralized by an acid group and R.sup.1 may form a ring together with R.sup.4 or R.sup.5 ; with the processing bath being used prior to or as a bleach bath or a blix bath, each containing a ferric ion complex as a bleaching agent.
