ABSTRACT:
An image-forming apparatus is disclosed. The image-forming apparatus includes a fixing unit. The fixing unit includes: a heating part including a heating element; a power storage unit including a chargeable and dischargeable capacitor and supplying power to the heating part so that the heating element of the heating part generates heat; and a controller controlling the operation of the power storage unit. When the image-forming operation of the image-forming apparatus is suspended by an abnormality, the controller performs control such that the capacitor is charged in accordance with its remaining amount of stored energy.
