ABSTRACT:
A method for forming an image is disclosed, which comprises heating a light-sensitive material having on a support, a light-sensitive silver halide, a binder and a dye releasing redox compound capable of releasing a dye through the reaction with the silver halide by heating, after or simultaneously with imagewise exposure, in the presence of a compound represented by the formula (A): ##STR1## wherein R is an aliphatic group with a valence of m+n, R.sup.1 is an aliphatic or aromatic group, and m and n are each an integer of 1 to 5. The presence of the compound markedly improves the stability of the light-sensitive material during its storage prior to the heat development.
