To obtain the heat-developable silver salt photographic sensitive material improved in occurrence of heat fog and superior in image storage stability by using a combination of a layer containing photosensitive silver halide and a layer containing a heat sensitive silver compound.
The combination of the layer containing the photosensitive silver halide and the layer containing heat sensitive silver compound is used or both layers are formed in a support. It is preferred that the layer containing the heat sensitive silver compound contains at least one of an organic polyhalogen compound and the compound represented by the formula (wherein, each of Ra and Rb is, independently, an optionally substituted aryl group and X is a Cl, Br, or I atom). It is preferred that this layer containing the heat sensitive silver compound contains a heterocyclic compound having a thiol group or a thione group.
