Abstract
A fixing device includes a fixing rotator, a heat source, a controller, a pressure rotator, and a nip formation pad. The controller controls the heat source such that a temperature of the fixing rotator is equal to a preset fixing temperature. The nip formation pad abuts the pressure rotator via the fixing rotator and forms a nip between the fixing rotator and the pressure rotator. When a print time of a previous job is longer than a prescribed time A and a next job is started within a prescribed time B after an end of the previous job, the controller corrects the preset fixing temperature during a time from a start of the next job to an entry of a print sheet into the nip and during a time from the entry of the print sheet into the nip to a lapse of a prescribed time C after the entry.
