A silver salt photothermographic dry imaging material including non-photosensitive aliphatic carboxylic acid silver salts; a photosensitive emulsion containing photosensitive silver halide grains; a silver ion reducing agent; a binder; and a cyan coloring leuco dye. A percentage of the photosensitive silver halide grains having a mean particle size of 0.01 or more .mu.m and 0.04 .mu.m or less is 5% or more by mass and 50% or less by mass of total photosensitive silver halide grains by conversion into a silver amount.
