Abstract:
1. A fixing device for fixing a toner image on a recording medium, comprising: an endless fixing member to rotate in a predetermined direction of rotation, formed in a loop; a pressing member contacting an outer circumferential surface of the fixing member to form a fixing nip between the fixing member and the pressing member through which the recording medium bearing the toner image passes; a temperature detector facing the fixing member to detect a temperature of the fixing member; and a heater facing the fixing member to heat the fixing member to a predetermined temperature based on a detection result provided by the temperature detector, the heater disposed with respect to the temperature detector with a circumferential distance A between the temperature detector and the heater along a circumference of the fixing member defined by the following formula: where v is a circumferential velocity of the fixing member rotating in the predetermined direction of rotation, T
