ABSTRACT:
The present invention provides a black and white photothermographic material having, on at least one surface of a support, an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions, and a binder, wherein 70% or more of a total projected area of the photosensitive silver halide is occupied by tabular grains having an aspect ratio of 2.5 or more, a mean projected area equivalent diameter of 0.5 μm to 8 μm, and a mean grain thickness of 0.02 μm to 0.2 μm, and a ratio of a number of sites capable of forming a development initiation point on a corner portion or a fringe portion of the photosensitive silver halide grain to all development initiation points is 50% or more. Also disclosed is an image forming method of forming a radiation image by using a fluorescent intensifying screen.
