More Information
Summary:A fixing device includes a heater that heats a fixing rotator and includes a first heating portion and a second heating portion substantially aligned with the first heating portion in an axial direction of the fixing rotator. A multi-view thermopile array detects a temperature of an outer circumferential surface of the fixing rotator at a plurality of spots thereon. A heater controller controls the first heating portion and the second heating portion individually based on the temperature of the fixing rotator detected at the plurality of spots thereon. A recording medium conveyance controller determines whether or not to convey the recording medium to the fixing nip based on an increased temperature detected at at least one of the plurality of spots on the fixing rotator.
