A photothermographic material including, on a support, at least two image forming layers each including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions, and a binder, wherein the image forming layers have spectral sensitivities that are different from each other, at least one layer of the image forming layers is a silver image forming layer which forms an image substantially constituted by a silver image, and at least one other layer of the image forming layers is a color image forming layer including a color image forming material. A photothermographic material which records a composite image made up of a silver image and a color image of different kinds of image information is provided. Particularly, a photothermographic material capable of forming a fusion image useful as a medical diagnosis image is provided.
