摘要： A photosensitive material drying device having a plurality of far infrared radiation heaters disposed in facing relationship so as to meet at right angles to the direction in which an exposed film is conveyed. The density of the film is measured before the film is heated by the far infrared radiation heaters. Upon heating of the film by the far infrared radiation heaters, the surface temperature of each of the far infrared radiation heaters is changed by a variable resistor in accordance with the measured density to thereby vary the amount of heat applied to the film. It is therefore possible to satisfactorily dry the film in accordance with a variation in the density of the film.
