Abstract
A photothermographic material including a substrate carrying on one surface thereof an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for a silver ion, and a binder, wherein the photosensitive silver halide has a silver iodide content of 40 to 100 mol %, and an average particle size of 5 to 80 nm, and the photothermographic material contains a compound of the following general formula (1); Q-(Y)n—C(Z1)(Z2)X General formula (1) wherein Q represents a heterocycle, Y represents a divalent connecting group, n represents 0 or 1, Z1 and Z1 each represent a halogen atom, and X represents a hydrogen atom or an electron withdrawing group.
