Abstract:
A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation; an opposed rotary body contacting the fixing rotary body to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed; a plurality of separation pawls separatably contacting an outer circumferential surface of the fixing rotary body to separate the recording medium discharged from the fixing nip from the fixing rotary body; a temperature detector contacting the outer circumferential surface of the fixing rotary body to detect a temperature of the fixing rotary body; and a fixing rotary body cleaner interposed between the plurality of separation pawls and the temperature detector in the direction of rotation of the fixing rotary body and contacting the outer circumferential surface of the fixing rotary body to clean the outer circumferential surface of the fixing rotary body.
