Abstract
At startup operation of a fixing device, a standby period during which a fixing belt and a pressure roller are heated until they reach a respective predetermined target temperature is shortened by heating the fixing belt to a temperature which is higher than the target temperature. In the fixing device, the fixing belt is spanned around an opposing roller and a heating roller. A pressure roller is provided in press-contact with the opposing roller via the fixing belt. A heater heats the fixing belt and the pressure roller so that temperatures of the fixing belt and the pressure roller reach a target temperature suitable for fixing a toner image. A recording material is conveyed through the rotating fixing belt and pressure roller to fix the toner image onto the recording material by heat and pressure.
