Abstract
The present invention provides a fixing device that can interrupt power supply to the resistive heat layer more reliably than the conventional technology, for example, at occurrence of abnormality. Electrodesandare provided on a circumferential surface of a fixing roller that includes a resistive heat layer that generates heat by receiving power supply, and power is supplied to the resistive heat layer when power supplying electrodesandthat are electrically connected to an electric power sourceare slidingly in contact with the electrodesand. An insulating tapeis attached on the electrode, and the drive controllerrotates a motoruntil the electrodeand the insulating tapeare in contact with each other, so that power supply to the resistive heat layer is interrupted.
