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); <?in-line-formulae description="In-line Formulae" end="lead"?>Q-(Y)<SUB>n</SUB>-C(Z<SUB>1</SUB>)(Z<SUB>2</SUB>)X <?in-line-formulae description="In-line Formulae" end="tail"?> 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.
