ABSTRACT:
A photothermographic material having, on at least one side of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive silver salt of a fatty acid, a reducing agent, and a binder, wherein 1) the photosensitive silver halide has an average silver iodide content of 40 mol % or higher, and 2) the photothermographic material includes a compound represented by the following formula (I) or a salt thereof:in-line-formulae description="In-line Formulae" end="lead"?R1—C≡C—R1′ Formula (I)in-line-formulae description="In-line Formulae" end="tail"?wherein R1and R1′ each independently represent a hydrogen atom, or a substituted or unsubstituted alkyl group, aryl group, or heterocyclic group, and R1and R1′ are not simultaneously a hydrogen atom. The invention provides a photothermographic material which exhibits high sensitivity and excellent image storability, and an image forming method.
