摘要： An image forming apparatus includes a fixing device, a temperature detector, and processing circuitry. The fixing device fixes a toner image on a surface of a sheet by heating of a heater. The temperature detector detects an internal temperature of the image forming apparatus. The processing circuitry switches a continuous print mode to an intermittent print mode when the internal temperature is equal to or higher than a first execution temperature during the continuous print mode. The processing circuitry cancels the intermittent print mode and switches to the continuous print mode when the internal temperature is equal to or lower than a first cancellation temperature. The processing circuitry causes the heater to stop heating the fixing device in the intermittent print mode when the internal temperature is higher than the first cancellation temperature even after a predetermined time has elapsed since a start of the intermittent print mode.

摘要： A fixing device includes an endless fixing belt rotatable in a given direction of rotation and a first nip formation pad contacting an inner circumferential surface of the fixing belt. A first driver sandwiches the fixing belt together with the first nip formation pad to rotate to drive and rotate the fixing belt. An opposed rotator is pressed against the first nip formation pad via the fixing belt to form a fixing nip between the fixing belt and the opposed rotator, through which a recording medium is conveyed. The opposed rotator is rotated frictionally by the fixing belt at the fixing nip.
