Abstract
An image forming apparatus includes a plurality of heaters, a plurality of temperature sensors, an object sensor, and control circuitry. The temperature sensors are formed at positions corresponding to the heaters. The object sensor is configured to detect an overlap region of a medium and the heaters. The control circuitry is configured to correct temperature information acquired by the temperature sensors, according to the overlap region detected by the object sensor and the positions of the temperature sensors, and control the heaters based on the corrected temperature information.
