ABSTRACT:
A light-sensitive material contains silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound or/and a cross-linkable polymer. According to the present invention, the light-sensitive material comprises a support and at least three image forming functional layers. The layers include a light-sensitive layer, a polymerizable layer and an image formation accelerating layer. The light-sensitive layer contains silver halide. The polymerizable layer contains the ethylenically unsaturated polymerizable compound or/and the cross-linkable polymer. The image formation accelerating layer contains a component having a function of accelerating image formation. The component is selected from a reducing agent, a base, a base precursor and a heat development accelerator. The uppermost layer of the light-sensitive material preferably contains a polyvinyl alcohol having a saponification degree of not less than 70%. The light-sensitive material of the present invention is heat-developable. The present invention is based on a new discovery that a light-sensitive material comprising three or more image forming functional layers can be developed. An image forming method using the light-sensitive material is also disclosed.
