Abstract
A photographic film curling correcting method and apparatus for correcting curling of a photographic film generated when the photographic film is stored for a long time in a cartridge in a state in which the photographic film is taken up around a spool shaft in a form of a roll, comprising the steps of: curvilinearly conveying the photographic film, which is withdrawn from the cartridge, so that the curling of the photographic film generated by taking up of the photographic film around the shaft becomes an opposite direction; and relaxing the curling by heating the photographic film while the photographic film is being curvilinearly conveyed, and taking up the photographic film, whose curling has been relaxed, into the cartridge again while cooling the photographic film. The curling of the photographic film can be corrected before developing processing when the photographic film is initially printed and before printing processing when the photographic film is printed a second time or times thereafter.
