PROBLEM TO BE SOLVED: To ensure good photographic performances such as sensitivity and fog even in the case of a monosheet type heat developable photosensitive material and to regulate the color tone of the photosensitive material in an arbitrary wavelength range. SOLUTION: The heat developable photosensitive material has at least (a) photosensitive silver halide, (b) a reducible silver salt, (c) a reducing compound of formula (1) or the formula Q1-NHNH-V6 (2), (d) a binder, (e) a coupler compound and (f) a contrast enhancer of formula (3), (4) or (5) on the same face of the base.
