摘要： The fixing device includes a pair of rotating bodies which conveys a recording medium between a nip; a heating unit which heats at least one of the rotating bodies; and a temperature detection unit which detects a temperature of at least one of the rotating bodies. The temperature detection unit detects a temperature change until an image forming apparatus is normally operated since the heating unit starts the heating, and the temperature change is stored. It is judged that the image forming apparatus is in an abnormal state when the temperature detection unit detects a temperature change different from the temperature change in the normal operation. A temperature control unit stops passage of current through the heating unit when it is judged that the image forming apparatus is in the abnormal state.

摘要： A cleaning device includes a cleaning web, a supply roller, a take-up roller, and a control section. Positioned in contact with a circumferential surface of a fuser roller, the web removes toner particles on the circumferential surface. The supply roller has the web wound thereon. The take-up roller takes up the web withdrawn from the supply roller. The control section controls rotation of the take-up roller. The control section performs a first process of causing the take-up roller to take up a first length of the web each time a predetermined taking-up condition is satisfied. The control section also performs a second process, instead of the first process, of causing the take-up roller to take up a second length of the web each time after a first predetermined number of the first processes are performed.

摘要： 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.
