    摘要： A fixing device includes a first support and a second support to rotatably support a fixing rotator at a first lateral end and a second lateral end of the fixing rotator in an axial direction thereof. A first stopper is mounted on the first support. A second stopper is mounted on the second support. A first skew restraint projects from an outer circumferential surface of the fixing rotator radially at the first lateral end of the fixing rotator in the axial direction thereof. A second skew restraint projects from the outer circumferential surface of the fixing rotator radially at the second lateral end of the fixing rotator in the axial direction thereof. The second skew restraint comes into contact with the second stopper as the fixing rotator moves in the axial direction thereof toward the first support.

    摘要： A fixing device includes a fixing rotator and a pressure rotator contacting the fixing rotator to form a fixing nip therebetween, through which recording media of a plurality of sizes are conveyed. The recording media create a plurality of non-conveyance spans on a lateral end of the fixing rotator in an axial direction thereof where the recording media are not conveyed. A heater is disposed opposite the fixing rotator to heat the fixing rotator. A multi-view thermopile array is disposed opposite an outer circumferential surface of the lateral end of the fixing rotator in the axial direction thereof and angled relative to the fixing rotator to detect a temperature of the fixing rotator. The thermopile array includes an inboard temperature detection element directed to a conveyance span on the fixing rotator where the recording medium of a decreased size is conveyed.

A heater is disposed opposite the fixing rotator to heat the fixing rotator. A thermopile array is disposed opposite an outer circumferential surface of the fixing rotator to detect a temperature of the outer circumferential surface of the fixing rotator. The thermopile array is tilted with respect to the outer circumferential surface of the fixing rotator to cause a bisector dividing a view angle of the thermopile array in an axial direction of the fixing rotator into two equal parts and a rotation axis of the fixing rotator to define an outboard angle and an inboard angle disposed inboard from the outboard angle in the axial direction of the fixing rotator and different from the outboard angle.

    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.
