摘要： A fixing device includes a fixing rotator and a pressure rotator pressed against a nip formation pad via the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator, through which a recording medium is conveyed. The nip formation pad includes an increased thermal conduction portion having an increased thermal conductivity and a decreased thermal conduction portion having a decreased thermal conductivity and being inboard from the increased thermal conduction portion in the axial direction of the fixing rotator. The increased thermal conduction portion is disposed opposite a non-conveyance span of the fixing rotator where the recording medium is not conveyed and includes an inboard edge inboard from a lateral edge of the recording medium toward a center of the recording medium in the axial direction of the fixing rotator by a predetermined first distance.

摘要： A fixing device includes a fixing rotator and a heater disposed inside the fixing rotator to heat the fixing rotator with radiant heat. A pressure rotator presses against the fixing rotator to form a fixing nip between the fixing rotator and the pressure rotator. A reflector is disposed opposite the heater to reflect the radiant heat radiated from the heater to the fixing rotator. The reflector includes a first parallel plane, a second parallel plane, and a third tilt plane. The second parallel plane is parallel to the first parallel plane and stepped with respect to the first parallel plane. The second parallel plane is disposed closer to the fixing nip and the heater than the first parallel plane. The third tilt plane bridges the first parallel plane and the second parallel plane and is disposed opposite the heater.
