Abstract
An image forming method, comprises the steps of, using an image forming medium containing a heat-diffusible coloring matter, a polymerizable polymer precursor and a polymerization initiator; causing said polymerizable polymer precursor of said image forming medium to selectively polymerize to form a latent image comprised of a polymerized area and an unpolymerized area; and PA1 heating said image forming medium on which said latent image has been formed and which is laid overlapping on an image receiving medium, so as to satisfy the following formula (A): EQU Tg.sub.1 .ltoreq.Ttrans.ltoreq.Tg.sub.2 (A) PA2 wherein Ttrans represents a temperature of said image forming medium, Tg.sub.1 represents a glass transition point of said unpolymerized area, and Tg.sub.2 represents a Glass transition point of said polymerized area, to diffusion-transfer said heat-diffusible coloring matter contained in said image forming medium to said image receiving medium, thereby forming an image comprised of said heat-diffusible coloring matter on said image receiving medium.
