To obtain a color image having decreased uneven densities in a jet water impartation system.

In this method forming images based on at least three colors of non-diffusive dye on a photosensitive material having at least three kinds of layers of photosensitive layers which include at least photosensitive silver halide, developing agents, dye donative couplers and binders on a transparent base, and in which the photosensitive wavelength regions and the absorption wavelength regions of the dyestuff formed by the developing agents and the dye-donative couplers vary from each other by using this photosensitive material and a processing material having processing layers contg. at least one base and/or base precursors on a base and subjecting the photosensitive material to imagewise exposure, then supplying water, superposing the photosensitive material and the processing material on each other and heating both materials for 5 to 60 seconds at 60 to 100°C, the water supply consists of a stage in which the water is supplied by spray of water drops at ≤0.01mm3, and the contact angle after 0.5 second since the water drop arrives at the photosensitive material is ≤50°.
