Abstract

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.
