Abstract
A fixing device includes a pressure rotator to press against a fixing rotator to form a fixing nip therebetween, through which a recording medium is conveyed. A cleaning web cleans one of the fixing rotator and the pressure rotator. A web driver displaces the cleaning web to change a contact portion of the cleaning web, which contacts the one of the fixing rotator and the pressure rotator. A controller performs a temperature maintenance and rotation control to heat and rotate the fixing rotator at a predetermined time when the fixing device is in a standby mode in which the recording medium is not conveyed through the fixing nip. The controller controls the web driver at a predetermined time to perform a standby mode cleaning control to change the contact portion of the cleaning web according to an implementation status of the temperature maintenance and rotation control.
