Abstract
Disclosed is a photothermographic material containing a silver salt of an organic acid, a silver halide and a reducing agent on a transparent support, which has, in silver iodide content distribution of total silver halide grains contained in the photothermographic material plotted with silver iodide content in abscissa and silver content in silver halide grains in ordinate, at least one maximum value in a silver iodide content range of less than 10 mol % and at least one maximum value in a silver iodide content range of 10 mol % or more. The photothermographic material shows low fog, little increase of fog and little sensitivity fluctuation during storage before light exposure.
