Abstract
In one embodiment, an operation state, standby state or installation environment of an image forming apparatus is detected or determined, and details of heating control of the surface temperature of rollers of a fixing apparatus are changed in accordance with the detected or determined state or environment. For example, when the operation state is a state in which printing on a last sheet of recording paper in a print job is complete, or when the operation state is a state in which printing on recording paper is interrupted, and, in addition, when the installation environment is a low-temperature and low-humidity environment and the image forming apparatus enters the standby state, heating of the rollers is respectively controlled to prevent unexpected and inappropriate changes in the surface temperature of the rollers.
