A photothermographic material having, on both sides of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions, and a binder, and an image forming method utilizing the same, characterized in that the image forming layer on a first side has an infectious development property, and the image forming layer on the other side does not have an infectious development property or has an infectious development property that is smaller than that of the image forming layer on the first side and wherein at least one of photographic properties selected from a sensitivity, a development proceeding property, a gradation, a maximum image density, and a color tone of a developed silver image is different from each other between that of the first side of the support and that of the other side of the support. The invention provides a double-sided type photothermographic material having improved photographic properties and an image forming method utilizing the same. |
