Abstract:
1. A fixing apparatus, comprising: a fixing rotation member; a rotation drive portion that rotates the fixing rotation member; a cleaning web sheet that cleans a circumferential surface of the fixing rotation member; a cleaning web sheet roller that takes up or feeds out the cleaning web sheet; a swing cam that is rotationally driven by the rotation drive portion; a rotation transmission portion that transmits a rotation drive force to the cleaning web sheet roller; a one way clutch that is provided on an input shaft of the rotation transmission portion; a swing lever that is connected to the one way clutch and biased so as to be brought into slide contact with the swing cam; and a separating portion that separates the swing lever from the swing cam, wherein if the swing cam is rotated by the rotation drive portion, the swing lever that is in slide contact with the swing cam repeatedly swings, the swinging of the swing lever is transmitted as an intermittent one-way rotation to the input shaft of the rotation transmission portion via the one way clutch, and the intermittent rotation is transmitted to the cleaning web sheet roller via the rotation transmission portion.
