A fixing device includes a radiating portion that radiates light on a recording medium on which a toner image is formed and that is transported along a transport path, a partition member that transmits the light radiated from the radiating portion and partitions between the radiating portion and the transport path, and a drive section that moves a scraping member scraping toner that adheres to the partition member and is heated by the radiation of the light from the radiating portion so as to contact a surface of the partition member of the transport path side.
