Abstract
An image forming apparatus capable of preventing toner offset is disclosed that includes an image forming mechanism and a fixing device. The fixing device includes a fixing rotator, a pressure rotator, a cleaning roller, a temperature detector, and a cooler. The temperature detector detects a surface temperature of at least one of the fixing rotator, the pressure rotator, and the cleaning roller. The cooler operates based on the temperature detected by the temperature detector. An image forming method and an image fixing method are also described.
