Abstract
Disclosed is a silver halide photosensitive material comprising a support and a photosensitive layer formed thereon. The photosensitive layer comprises at least a photosensitive silver halide emulsion, a developing agent, a compound which forms a dye by a coupling reaction with an oxidized form of the developing agent, and a binder. The silver halide photosensitive material after the exposure thereof is put together with a processing material, which comprises a processing layer containing at least a base and/or a base precursor, in the presence of water supplied between the layer of the silver halide photosensitive material and the layer of the processing material in an amount ranging from 1/10 to the equivalent of an amount which is required for the maximum swelling of the total of the layers of these materials excluding back layers thereof, and these materials are heated to form a color image in the silver halide photosensitive material, in which the photosensitive layer comprises gelatin which is modified so that the interaction thereof with silver is reduced, and a silver halide emulsion in which tabular silver halide grains, each having an aspect ratio of 2 or more, account for 50% or more of the total projected area of the silver halide grains of the emulsion. Also disclosed is a method for forming an image by using this silver halide photosensitive material.
