To obtain the processor of a photographic material by surface coating by which sensitometry having enhanced efficiency and reproducibility is given.

The processor of the photographic material is provided with a means supporting the photographic material 18 to be processed, a means for heating the material 18, a means for coating the surface of the material 18 being most distant from a supporting body with photograph processing liquid, the temperature control means of the heating means of the material 18 and a sensor 50 for measuring the temperature of the surface of the material 18 being most distant from the supporting body. Besides, the supporting body provided with at least one silver halide emulsion layer on at least one surface is included in the processor of the photographic material.
