A method for heat-treating a photographic film while conveying, which comprises the steps of: passing the photographic film through from 2 to 100 rolls disposed so that gaps between the adjacent rolls are within the range of from 0.1 cm to 50 cm; and heat-treating the photographic film during the conveyance, wherein the photographic film comprises a support having coated thereon at least one layer. Also disclosed is a method for heat-treating a photographic film, which comprises the steps of: heat-treating a photographic film; and winding the heat-treated film, wherein the heat-treated film is cooled before the winding, the cooling rate in the temperature range from the glass transition temperature (Tg) of the film + 40 DEG C to the Tg - 10 DEG C being at 0.01 DEG C/second to 10 DEG C/second. Further disclosed is a photographic film having a width direction and a lengthwise direction, and having a thickness unevenness along the film's width direction is from 2 mu m to 300 mu m. |
