A photothermographic material having, on at least one side of a support,
an image forming layer containing at least a photosensitive silver
halide, a non-photosensitive organic silver salt, a reducing agent, and a
binder, and at least one non-photosensitive layer which is disposed on
the same side as the image forming layer and farther from the support
than the image forming layer, wherein (1) 50% by weight or more of the
binder is a polymer latex having a monomer component having an acid
group, and (2) the polymer latex has a core/shell structure having a core
part and a shell part, and the monomer component having an acid group in
the core part is 2 mol % to 20 mol % of a total amount of the monomer
component having an acid group in the polymer latex. The invention
provides a photothermographic material which exhibits excellent image
uniformity with low fog.
