Abstract
A photosensitive material drying device comprising a plurality of far infrared radiation heaters for heating a film are disposed so as to meet at right angles to a direction in which a film is conveyed. The reflectivity of each reflector disposed along the film conveying direction is set so that the reflectivity of each of longitudinally-extending ends of the film is greater than a longitudinally-extending central portion thereof. Therefore, the amount of reflected heat received by the film is associated with the reflectivity. That is, the amount of heat generated from the far infrared radiation heater at longitudinally-extending ends thereof is lower than that at a longitudinally-extending central portion thereof, whereas the amount of heat radiated over the film via the reflector is set such that the amount of heat at the central portion of the far infrared radiation heater is greater than that at the longitudinally-extending ends thereof. Therefore, the amount of heat received by the film becomes uniform along the transverse direction of the film, thereby making it possible to uniformly dry the film and prevent uneven dryness and gloss from occurring.
