A photothermographic material comprising, on one surface of a support, at least one kind of photosensitive silver halide, a silver salt of an organic acid, a reducing agent for silver ions, and a binder, wherein (1) said material further comprises two or more kinds of organic polyhalogenated compounds, and (2) a melting point of a mixture which consists of the organic polyhalogenated compounds in the same content ratio as the content ratio of said compounds in the photothermographic material is in the range of from −10° C. to 50° C. relative to a heat development temperature for the photothermographic material. The photothermographic material of the present invention shows high sensitivity and superior storability before heat development, and the material can be used for medical images, photoengraving and the like.
