Photothermographic material and image forming method

Abstract

A photothermographic material including at least a photosensitive silver halide, a non-photosensitive organic silver salt, and a reducing agent for thermal development, and further including at least two dyes having maximum absorption wavelengths different from each other, wherein the difference between the maximum absorption wavelengths is from 10 nm to 50 nm, a maximum absorption wavelength of a first dye corresponds to a wavelength of a first laser for imagewise exposure, and a maximum absorption wavelength of a second dye corresponds to a wavelength of a second laser for imagewise exposure. Moreover, an image forming method using a sheet of the photothermographic material, wherein a part of the sheet is imagewise exposed using a laser while another part of the sheet that has already been imagewise exposed is thermally developed, and a distance between the exposure portion and thermal developing portion is 50 cm or less, is provided.
