FIXING DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME

摘要

A fixing device includes a heater, a fixing rotator, a pressure rotator, a slider, and a controller. The fixing rotator is heated by the heater. The pressure rotator presses at least a portion of the fixing rotator and forms a nip between the pressure rotator and the fixing rotator. The fixing rotator fixes an unfixed toner image on a recording material in the nip. The slider slides over a surface of the fixing rotator. The controller causes the slider to perform a first sliding operation for a predetermined time after a predetermined condition is satisfied. The controller causes the slider to perform a second sliding operation for a time equal to or less than the predetermined time at earlier timing than when the predetermined condition is satisfied, in addition to the first sliding operation.
