ABSTRACT:
A drying device for an automatic developing apparatus has a plurality of far infrared radiant heaters and fans provided in a squeezing portion, which is located between a processing area for a processing liquid and a drying area, for drying a film in accordance with a predetermined drying control pattern, in a constant-rate drying area until the film reaches a drying point. When the film is conveyed into the drying area, the film is dried by the plurality of far infrared radiant heaters and fans positioned in a first drying portion until the film moves from the constant-rate drying region to a predetermined decreasing-rate drying region. When the film is conveyed from the first drying portion to a second drying portion, a rate of change of a surface temperature of the film with respect to the drying time until the film reaches the drying point is maintained at a constant value. Thus, the drying process is completed without unsatisfactory drying and inconveniences such as drying marks. This permits the drying time of the film to be reduced, and permits the film to be dried optimally without unsatisfactory drying.
