Abstract
A fixing device includes: a fixing unit that transports a recording medium as nipped between a pressure rotary member and a heating rotary member, to thereby fix a developer image on the recording medium; temperature detectors that detect temperatures of regions of the pressure rotary member; cooling units that cool the detected regions; and a controller that controls the cooling units to, if a temperature difference between the regions is more than a set temperature difference, execute first cooling for reducing the temperature difference to the set temperature difference or less, and to, if a width of the recording medium perpendicular to a transport direction thereof used in an immediately preceding image formation is equal to or less than a preset width, execute, subsequently to the first cooling, second cooling for cooling the pressure rotary member for a preset time.
