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.
