ABSTRACT:
An image forming method of imagewise exposing and heating a light-sensitive material is disclosed. The light-sensitive material comprises a support and a light-sensitive layer provided thereon. The light-sensitive layer contains silver halide, a reducing agent, an ethylenically unsaturated polymerizable compound, a color image forming substance and a base precursor. The silver halide, the reducing agent, the polymerizable compound, the color image forming substance and the base precursor are contained in microcapsules which are dispersed in the light-sensitive layer. According to the present invention, the support is made of a thin polymer film having a thickness of not more than 75 .mu.m. The light-sensitive material is heated from the side of the support for 0.1 to 5 seconds.
