An image forming method is conducted by subjecting a dry silver salt image forming medium to imagewise exposure and heating to form a light-absorbing organic compound. Thereafter, the medium is subjected to polymerization exposure to imagewise polymerize the medium based on the formation pattern of the light-absorbing compound. The light-absorbing organic compound has specific sensitivities to light in order to maximize contrast.

摘要:
A photosensitive member suitable for multi-color image formation is obtained by forming a plurality of photosensitive layers laminated on a substrate. Each photosensistive layer comprises a matrix phase and particles dispersed therein. The matrix phase contains a photosensitive silver salt, an organic silver salt and a reducing agent which react with each other on exposure and heating to form a light-absorbing organic compound. The particles contain a heat-diffusive colorant, a polymerizable polymer precursor and a photopolymerization initiator. The light-absorbing organic compound in a photosensitive layer being capable of absorbing a wavelength of light to which the photopolymerization initiator in the photosensitive layer is sensitive. Because the heat-diffusive colorant, the polymerizer and the initiator are contained in the particles, the diffusion of the heat-diffusive colorant can be effectively controlled to prevent color fog.
