Abstract
The fixing device includes a heating roller made of magnetic metal and heated by electromagnetic induction; a fixing roller disposed parallel to the heating roller; an endless toner heating medium belt bridged across the heating roller and the fixing roller, and a press roller pressed to the fixing roller via the toner heating medium. The press roller rotates in the same direction as the toner heating medium belt to form a fixing nip region, and the belt is heated by the heating roller and rotated by the two rollers. The construction of the present invention achieves stable temperature control of the toner heating medium, and provides a stable fixing quality of the toner image.
