Abstract
A photothermographic imaging material having a support; a photosensitive layer containing photosensitive silver halide particles on one face of the support; and a non-photosensitive layer provided on a side of the support where the photosensitive layer is provided. At least one of the photosensitive layer and the non-photosensitive layer contains an organic silver salt, a reducing agent, a compound represented by the Formula (1) and a compound represented by the Formula (2a).
