The present invention provides a black and white photothermographic material having, on at least one side of a support, an image forming layer including at least a photosensitive silver halide and a non-photosensitive organic silver salt, and a non-photosensitive layer including at least a coupler, wherein at least one of the image forming layer and the non-photosensitive layer includes a color developing agent; a grain density of the photosensitive silver halide in the image forming layer is from 20 grains/μm3 to 103 grains/μm3; and an optical density of an image formed by imagewise exposing and thermally developing the black and white photothermographic material satisfies the following equation (A): 0.02<Dc<D/4 Equation (A) wherein D represents a value of an optical density in a range of from 1.0 to 2.0; and Dc represents an optical density obtained by the dye in the optical density of the image.
A black and white photothermographic material comprising, on at least one side of a support, an image forming layer comprising at least a photosensitive silver halide and a non-photosensitive organic silver salt, and a non-photosensitive layer comprising at least a coupler, wherein at least one of the image forming layer and the non-photosensitive layer comprises a color developing agent whose oxidation product reacts with the coupler to form a dye;
