| 摘要 |
The invention provides a photothermographic material including, 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, wherein: the photosensitive silver halide has an average silver iodide content of 40 mol% or higher, and at least 50% of a projected area of total grains of the photosensitive silver halide is occupied by tabular grains having an aspect ratio of 2 or more; and 50% by weight or more of the binder is formed by a polymer latex containing the following monomer component from 10% by weight to 70% by weight: Formula (M) CH2=CR<01>-CR<02>=CH2 wherein R<01> and R<02> each independently represent one selected from a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a halogen atom, and a cyano group, provided that both of R<01> and R<02> are not hydrogen atoms simultaneously. <??>The invention provides a photothermographic material and an image forming method utilizing the same which give an image with little haze, high image quality, and excellent pressure resistance.
