摘要: A fixing device for fixing a toner image on a recording medium includes a pressing member provided outside a loop formed by a fixing member to press the fixing member against a nip formation member provided inside the loop formed by the fixing member. A heat generator support is provided inside the loop formed by the fixing member to support a heat generator that generates heat to be transmitted to the fixing member. A temperature detector is provided downstream from the heat generator and upstream from the nip formation member in a direction of rotation of the fixing member to detect a temperature of the fixing member. A controller is connected to the temperature detector and the heat generator to control heat generation of the heat generator based on the temperature of the fixing member detected by the temperature detector.

摘要: A fixing device includes an endless fuser belt, a contact member, a pressure member, a heater, a first thermometer, a second thermometer, and a controller. The fuser belt is looped into a generally cylindrical configuration. The contact member extends inside the loop of the fuser belt. The pressure member extends with the fuser interposed between the contact member and the pressure member. The pressure member is pressed against the contact member through the fuser belt to form a fixing nip. The heater includes a first heating element and a second heating element. The first heating element heats the fuser belt at a first position. The second heating element heats the fuser belt at a second position. The first thermometer detects a first temperature of the fuser belt. The second thermometer detects a second temperature of the fuser belt. The controller controls each of the first and second heating elements.
