    摘要： A fixing device includes a nip formation pad pressing against a pressure rotator via a fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. The nip formation pad includes a base and a first thermal conductor sandwiched between the base and the fixing rotator at the fixing nip and having a first thermal conductivity greater than a basic thermal conductivity of the base. A first heater and a second heater are disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. A rotatable light shield moves to a shield position where the light shield is interposed between the second heater and the fixing rotator to shield the fixing rotator from the second heater. The second heater is disposed at a location where the light shield screens the second heater more readily than the first heater.

    摘要： 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.

    摘要： An image forming apparatus includes a fixing rotator and an opposed rotator pressed against the fixing rotator to form a fixing nip therebetween, through which a recording medium bearing a toner image is conveyed. A heater heats the fixing rotator. A temperature sensor contacts the opposed rotator to detect a temperature of the opposed rotator. A conveyor conveys the recording medium to the fixing nip. A driver drives the conveyor. A controller, operatively connected to the temperature sensor and the driver, controls the driver to drive the conveyor to convey the recording medium to the fixing nip based on the temperature of the opposed rotator detected by the temperature sensor. The controller causes the driver to be ready to drive the conveyor when a change in the detected temperature of the opposed rotator per unit time reaches a predetermined threshold.
