    摘要: The present invention provides a black and white photothermographic material having, 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 for silver ions, and a binder, as well as an image forming method. The black and white photothermographic material is characterized in that 50% or more of a total projected area of the photosensitive silver halide is occupied by tabular grains having a (111) face as a major face; the tabular grains have at least 2 parallel twin crystal planes in a grain; and a variation coefficient of a distribution of distances between closest twin crystal planes is 20% or less. Also provided is an image forming method that includes image exposure using fluorescent intensifying screens and thermal development. According to the invention, a black and white photothermographic material and image forming method realizing high image quality with favorable color tone of developed silver images are provided.

    摘要: A silver halide emulsion comprising silver halide grains. In them, 60 or more percent of the total area of all silver halide grains are occupied by tabular silver halide grains having a circle equivalent diameter of 0.6 .mu.m or less, an aspect ratio of 1.5 or more, and having dislocation lines substantially localized only in the fringe portions thereof. Also, 50 or more percent of the number of all silver halide grains are occupied by tabular silver halide grains having 10 or more dislocation lines per grain. In addition, the surface silver iodide content of all silver halide grains is 3 mol % or less when analyzed by X-ray photoelectric spectroscopy (XPS).
