ABSTRACT:
A method of forming color image, comprising processing a silver halide color photosensitive material with a development processing solution containing a color developing agent, the silver halide color photosensitive material comprising a support and, superimposed thereon, a blue-sensitive layer unit composed of at least one silver halide emulsion layer, a green-sensitive layer unit composed of at least two silver halide emulsion layers, a red-sensitive layer unit composed of at least two silver halide emulsion layers and at least one non-light-sensitive layer, wherein the development processing solution or processing solution applied to the silver halide color photosensitive material before the use of the development processing solution contains compound (A), the compound (A) being a heterocyclic compound having three or more heteroatoms which when added, is capable of substantially enhancing the sensitivity of the silver halide color photosensitive material as compared with that exhibited when not added.
