Disclosed is a photothermographic material containing a photosensitive silver halide, a non-photosensitive silver salt of an organic acid, a reducing agent for silver ions and a binder on one surface of a support, wherein a ratio of twin crystal grains of the photosensitive silver halide is 1.0% or less with respect to the total grain number of the photosensitive silver halide. This photothermographic material shows high sensitivity, low fog, high Dmax (maximum density) and little increase of fog during storage. <IMAGE>
