摘要： A fixing device includes a drive roller, a driven roller driven to rotate by the drive roller, and a braking force applicator. The driven roller presses against the drive roller to form an area of contact between the drive roller and the driven roller, through which a recording medium bearing a toner image passes. The braking force applicator applies a braking force to the driven roller to generate a shear force between the drive roller and the driven roller. The shear force acting between the drive roller and the driven roller when the drive roller and the driven roller rotate is in a range of from 15N to 25N.

摘要： A fixing device includes a fixing rotator including a primary portion and a secondary portion disposed outboard from the primary portion in an axial direction of the fixing rotator. A pressure rotator contacts the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed. A primary heater heats the primary portion of the fixing rotator. A secondary heater heats the secondary portion of the fixing rotator. A primary temperature detector is isolated from the fixing rotator and detects a temperature of the primary portion of the fixing rotator. A secondary temperature detector contacts the fixing rotator and detects a temperature of the secondary portion of the fixing rotator. The primary temperature detector has a thermal time constant that is smaller than a thermal time constant of the secondary temperature detector.

摘要： A fixing device includes a fixing roller and a pressing roller that are in pressure contact with each other. A separating plate is placed opposite to the fixing roller with a certain gap in between them. Positioning portions are installed on the separating plate to be in contact with width-direction ends of the fixing roller for determining the gap. The positioning portions are arranged such that edges of contact portions of the positioning portions on the width-direction center side in contact with the fixing unit are positioned outside an image area and inside a paper-passing area for a recording medium of a maximum passing-capable size.
