ABSTRACT:
An image forming process comprising the steps of: imagewise-exposing a heat developable light-sensitive material comprising a support having thereon at least a light-sensitive silver halide, a binder and a dye-donating compound, wherein the dye-donating compound forms or releases a diffusive dye corresponding or reversely corresponding to a reduction reaction of the silver halide into silver; supplying water to the exposed material; heat developing the water-supplied material to form a diffusive dye image therein; and transferring the diffusive dye image onto a dye-fixing element, wherein the water-supplying step comprises jetting of a water droplet having a volume of not more than 0.01 mm.sup.3, and the light-sensitive material has a contact angle of not more than 50 degrees as determined at 0.5 second after the impact of the water droplet onto the light-sensitive material.
