| 摘要 |
The present invention provides a black and white photothermographic material including at least a photosensitive silver halide, a non-photosensitive organic silver salt, and a binder on a support, wherein the black and white photothermographic material contains a reducing agent represented by formula (1) and a coupler which reacts with an oxidation product of the reducing agent to form a dye and is represented by formula (2), (3), (4), or (5); and a density obtained by the dye at a maximum absorption wavelength of the dye is from 0.005 to 0.5 when an image density is 2.0. A photothermographic material which exhibits excellent image tone and excellent image storage stability is provided.
