<p>A photothermographic material including an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder on the same surface of a support, wherein the photothermographic material contains a compound having an adsorption group to silver halide and a reducing group, or a precursor of the compound, and satisfies one of the following conditions:
1) the photothermographic material contains a development accelerator;
2) the non-photosensitive organic silver contains silver behenate in an amount of not less than 80% by mole, and the binder has a glass transition temperature (Tg) of 45°C or less; or
3) the photothermographic material contains at least one compound represented by the following formula (H) ;
Q-(Y)<Sub>n</Sub>-C(Z<Sub>1</Sub>)(Z<Sub>2</Sub>)X
wherein, in formula (H), Q represents an alkyl group, an aryl group or a heterocyclic group; Y represents a divalent linking group; n represents 0 or 1; Z<Sub>1</Sub> and Z<Sub>2</Sub> each independently represent a halogen atom; and x represents a hydrogen atom or an electron attracting group.</p> |
