摘要： There is provided a method for forming an image, which comprises processing a silver halide color photographic material that has a high-silver-chloride silver halide emulsion and which contains in the photographic material a nitrogen-containing heterocyclic compound, the solubility product of which for the silver salt is in a limited range, with a color developer containing chloride ions and bromide ions in a limited concentration, respectively. The method is excellent in forming an image that can be performed rapidly, and is high in sensitivity, in prevention of processing color-mixing, and in less fluctuation of the photographic quality involved in continuous processing.
