Abstract
An image forming apparatus includes a fixing device, a temperature sensor that detects a temperature of an end of the fixing device, and a blower unit that supplies air to the end of the fixing device to cool the end of the fixing device. In addition, a processor circuit is configured to control a cooling level by the blower unit in accordance with the temperature of the end of the fixing device detected by the temperature sensor, to predict, based on a parameter depending on the cooling level, a discharge amount of ultra fine particles that are discharged from the image forming apparatus, and to control an image forming operation by the image forming apparatus such that the discharge amount of ultra fine particles is reduced in accordance with the discharge amount predicted by the processor circuit.
