    • A photosensitive material comprises a photosensitive silver halide, an organic silver salt, a reducing agent, a polymerizable polymer precursor, a photopolymerization initiator and a heat-diffusible coloring matter. As a preferred embodiment, the photosensitive material comprises a photosensitive layer containing the photosensitive silver halide, the organic silver salt and the reducing agent, a polymerizing layer containing the polymerizable polymer precursor and the photopolymerization initiator, and a coloring material layer containing the heat-diffusible coloring material. A image forming method employing the photosensitive material comprises the steps of a) subjecting the photosensitive material to imagewise exposure; b) heating the photosensitive material; c) subjecting to whole areas exposure at least the polymerizing layer; and d) heating at least the coloring material layer to transfer the heat-diffusible coloring matter to an image-receiving material, thus forming a color image.
