Abstract:
1. A fixing device comprising: a fixing rotator rotatable in a predetermined direction of rotation; an abutment rotator contacting the fixing rotator to form a fixing nip therebetween through which a recording medium is conveyed; a heater disposed opposite the fixing rotator to heat the fixing rotator; and a thermopile array 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 being 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.
