Abstract
A color image is formed by subjecting a silver halide photosensitive material comprising at least a photosensitive silver halide, a two equivalent coupler, a binder, and a substantially water-insoluble basic metal compound on a support, to development with a processing solution comprising a complexing compound capable of complexing reaction with the metal in ionic form of said substantially water-insoluble basic metal compound in the presence of water to release a base.
