Abstract
An image forming apparatus includes a heater, a first temperature sensor, a second temperature sensor, and processing circuitry. The heater is configured to heat a medium on which an image is formed. The first temperature sensor is configured to measure a temperature of the heater. The second temperature sensor is configured to measure a temperature of a region heated by the heater. The processing circuitry is configured to control the temperature of the heater. The processing circuitry is configured to control the heater based on a comparison between a measured temperature of the first temperature sensor and a first threshold value, and a comparison between a measured temperature of the second temperature sensor and a second threshold value.
