PROBLEM TO BE SOLVED: To provide a heat-developable photosensitive material having photographic characteristics of high contrast and low fog and good storage stability to be used for a photomechanical process, especially, a scanner and an image setter. SOLUTION: The heat-developable photosensitive material contains a nonphotosensitive silver salt and photosensitive silver halide and a binder on a support, and the image forming layer containing this photosensitive silver halide uses a polymer latex amounting to >=50 weight% of the binder and having a glass transition point of -30 deg.C-40 deg.C, and this silver halide is spectrally sensitized in the wavelength region of 750-1400 nm, and this image forming layer and/or its adjacent layer contains at least one kind of compound represented by the formula in which R is an H or halogen atom or a 1-4 C alkyl, aryl, amino, nitro, optionally substituted carboxylic acid, or its salt, sulfonic acid on its salt.
