ABSTRACT:
The invention provides a photothermographic material containing an image forming layer having at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder on at least one side of a support, an outermost layer on the same side of the support as the image forming layer, and a non-photosensitive intermediate layer between the outermost layer and the image forming layer, wherein 50% by weight or more of a binder of the non-photosensitive intermediate layer is formed by a hydrophobic polymer latex, the outermost layer has a mean thickness of from 0.1 μm to 0.45 μm, and the non-photosensitive intermediate layer has a variation coefficient of a thickness distribution of 50% or less based on a mean thickness of the non-photosensitive intermediate layer. A photothermographic material, which exhibits reduced image unevenness and excellent image storage stability, is provided.
