Abstract:
    Provided are a photothermographic material which includes, on at least one side of a support, an image forming layer containing at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, and is X-ray exposed with a fluorescent intensifying screen, wherein (1) the photosensitive silver halide includes tabular grains having a mean aspect ratio of 2 to 100 and a mean equivalent spherical diameter of 0.3 mum to 10 mum, (2) an exposure value necessary for obtaining an image density of fog 0.5 after exposing the photothermographic material with monochromatic light having the same wavelength as the main emission peak wavelength of the fluorescent intensifying screen and having a half width of 15 nm -5 nm and thermally developing the photothermographic material is from 1x10
