Image forming method

An image formation method in which a photosensitive element comprising a support carrying thereon a photosensitive layer comprising at least silver halide particles, coloring developer, coupler and binder is exposed in image-wise fashion, then, a first treating element comprising a support carrying thereon a treating layer comprising at least a base and/or base precursor is laminated on said photosensitive element so that the treating layer of the first treating element faces the photosensitive layer of the photosensitive element and the resultant laminate is heated for 5 to 60 seconds at a temperature of 60 to 100.degree. C. in the presence of water in an amount of 1 cc/m.sup.2 to 50 cc/m.sup.2 between the photosensitive layer of the photosensitive element and the treating layer of the first treating element, then, the photosensitive element is separated from the first treating element, then, a second treating element comprising a support carrying thereon a solvent for silver halide and a treating layer comprising at least an acidic polymer is laminated on said photosensitive element so that the treating layer of the second treating element faces the photosensitive layer of the photosensitive element and the resultant laminate is heated for 2 to 60 seconds at a temperature of 40 to 100.degree. C. in the presence of water in an amount of 1 cc/m.sup.2 to 50 cc/m.sup.2 between the photosensitive layer of the photosensitive element and the treating layer of the second treating element, then, the photosensitive element is separated from the second treating element, to form an image on the photosensitive element.
