Abstract
In a fixing device including a fixing roller, a pressure roller and an external heating section, a scraper is arranged to contact a circumferential surface of an external heating belt and scrape toner and the like on the circumferential surface to thereby clean the circumferential surface. In addition, a material that has higher adherence to toner than on a circumferential surface of the fixing roller is used for the external hating belt to thereby peel the toner and the like on the circumferential surface of the fixing roller and clean the circumferential surface of the fixing roller. Further, as a vibration applying section adapted to apply vibration to the scraper, a first contact/separation section adapted to contact/separate the external heating section with/from the fixing roller is provided. Vibration is applied to the scraper by the first contact/separation to peel the toner and the like off the scraper.
