In a photothermographic element comprising a non-photosensitive silver salt, a photosensitive silver halide, and a binder on a support, a latex of a polymer having a Tg of -30 DEG C. to 40 DEG C. constitutes at least 50% by weight of the binder in an image forming layer containing the silver halide, and the image forming layer or a layer disposed adjacent thereto or both contain a nucleating agent and a diphosphorus pentoxide-derived compound. The element produces a low fog, high contrast image. |
