摘要： A fixing apparatus and an image forming apparatus of the present invention are arranged so that a fixing control section causes a fixing roller to additionally rotate so that the additional rotation corresponds to a driving delay time also after turning OFF an external heating roller heater when shifting from a temperature raising step in which surface temperature of the fixing roller is raised so as to be equal to a preset fixing temperature to a standby mode and when turning OFF the external heating roller heater and stopping the fixing roller. As a result, it is possible to provide a fixing apparatus and an image forming apparatus in which a surface of a fixing roller is free from deterioration or breakage caused by local heating carried out by an external heating roller.

摘要： A fixing control section of a fixing apparatus according to the present invention includes an end section priority temperature control mode. In the end section priority temperature control mode, the fixing control section temporarily turns off a main heater heating a center section of a fixing roller among a plurarity of heaters disposed inside the fixing roller in a case where a surface temperature of the end section of the fixing roller has reached a preset upper-limit fixing temperature, even if the surface temperature of the center section of the fixing roller is lower than a preset fixing temperature. As a result, destruction of the fixing roller can be prevented by a simple arrangement in the fixing apparatus which includes a plurarity of the heaters disposed inside the fixing roller.

摘要： In a fixing apparatus of the present invention, an end section fixing control temperature changing section selects an end section fixing control temperature in accordance with the number of paper sheets that have been processed in one continuous printing process. A sub-heater on/off determining section turns on or off a sub-heater in accordance with a temperature detected by an end section temperature sensor and the end section fixing control temperature selected by the end section fixing control temperature changing section. This prevents the occurrence of fixing failure even in continuous printing with respect to large-size paper sheets in an arrangement in which a temperature sensor is disposed outside a maximum-size sheet passing region at an end section of a fixing roller and controls energization of a heater which is disposed corresponding to the end section of the fixing roller in accordance with a temperature detected by the temperature sensor.

摘要： An arrangement for locking a cover which can be opened and closed to cover an opening of a vehicle such as a door or luggage lid is disclosed. Means for detecting the presence or absence of an occupant within the vehicle as well as means for detecting the open or closed condition of the cover are provided. When the absence of an occupant is detected and the closed condition of the opening cover is detected, a lock mechanism which blocks an opening movement of the opening cover is locked. In this manner, if an occupant has forgotten to lock a door or doors when getting off his vehicle, the doors are automatically locked, thus reliably preventing a theft or tampering with the vehicle.

摘要： An image forming apparatus (100) includes a discharge section (210), a paper receiving tray (93), a first detecting section (211), a lever (220), a second detecting section (230) and a decision section (240). The first detecting section (211) is disposed in the discharge section (210), and detects a paper jam. The second detecting section (230) detects a swinging state of the lever (220) from a first position at which the lever (220) is not in the process of receiving an action of the paper sheet to a second position. The decision section (240) judges an occurrence factor in a paper jam to be a user-induced factor when the second detecting section (230) detects a state in which the lever is at the first position in a state where the first detecting section (211) detects the paper jam. Also, the decision section (240) judges the occurrence factor in the paper jam to be an image forming apparatus-induced factor when the second detecting section (230) detects a state in which the lever is swung over the first position in the state where the first detecting section detects the paper jam.

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.
