摘要： A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation and a heater disposed opposite and heating the fixing rotary body. A heat shield is movable in a circumferential direction of the fixing rotary body and interposed between the heater and the fixing rotary body to shield the fixing rotary body from the heater. A driver is connected to the heat shield to drive and move the heat shield within a circumferential moving span in the circumferential direction of the fixing rotary body. An abnormal temperature detector detects an abnormal temperature of the fixing rotary body that is not lower than a predetermined temperature. The abnormal temperature detector is disposed opposite a circumferential outboard span outboard from the circumferential moving span of the heat shield in the circumferential direction of the fixing rotary body.

摘要： A fixing device includes a fixing rotator heated by a heater and a pressing rotator pressed against the fixing rotator to form a fixing nip therebetween, through which a recording medium bearing a toner image is conveyed. A heat shield interposed between the heater and the fixing rotator is movable in a circumferential direction of the fixing rotator to shield the fixing rotator from the heater in a variable axial shield span of the fixing rotator. The fixing rotator performs fixing rotation to convey the recording medium through the fixing nip while heating the recording medium and supplemental rotation other than fixing rotation. The heat shield moves to a decreased shield span position where the heat shield shields the fixing rotator from the heater in a decreased axial shield span of the fixing rotator during supplemental rotation thereof.

摘要： A fixing device includes a heat source; a fixing member looped into a generally cylindrical shape to rotate in a circumferential direction thereof and partially heated by the heat source and to heat a surface of a recording medium bearing an unfixed toner image to fix the unfixed toner image thereon in a fixing process; a rotary pressing member disposed facing the fixing member to form a nip therebetween, through which the recording medium is transported in a transport direction; and a rotation driver to rotate one of the fixing member and the pressing member. In a case in which the fixing member is halted for a reason other than the fixing process while power of the fixing device is on, electric power is not supplied to the heat source and the fixing member is rotated by a predetermined amount or more after the fixing member is halted.

摘要： A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation and a heater disposed opposite and heating the fixing rotary body. An opposed body contacts the fixing rotary body with releasable pressure therebetween to form a fixing nip therebetween through which a recording medium is conveyed. A heat shield is interposed between the heater and the fixing rotary body and movable in a circumferential direction of the fixing rotary body between a home position where the heat shield is disposed opposite the heater indirectly and a shield position where the heat shield is disposed opposite the heater directly to shield the fixing rotary body from the heater. A controller is operatively connected to the heat shield to move the heat shield to the home position when a print job is finished.

摘要： A fixing device includes a support member disposed to support a nip formation member on an inner peripheral surface of a fixing belt. The support member includes a parallel portion that supports the nip formation member and extends parallel to a sheet transport direction in a nip portion, and a rise portion that extends from the parallel portion in a direction drawn apart from the nip portion. The rise portion is inclined to the parallel portion such that an inclination direction of the rise portion is substantially parallel to a virtual straight line connecting a center of rotation of the fixing belt and an inlet point of the nip portion or falls within a range of rotational angles of ±15° by which the virtual straight line is rotated around the center of rotation of the fixing belt.
