摘要： A fixing device includes a nip formation pad to press against a fixing rotator. A primary heater is disposed opposite the fixing rotator in a primary heating span spanning in an axial direction of the fixing rotator to heat the primary heating span of the fixing rotator from which heat is conducted to the nip formation pad with a primary conduction. A secondary heater is disposed opposite the fixing rotator in a secondary heating span that is outboard from the primary heating span in the axial direction of the fixing rotator. The secondary heater is interposed between a first nip formation portion and a second nip formation portion of the nip formation pad to heat the secondary heating span of the fixing rotator through the nip formation pad from which heat is conducted to the fixing rotator with a secondary conduction greater than the primary conduction.

摘要： A fixing device includes a primary heater, a secondary heater, and a tertiary heater to heat a primary heating span, a secondary heating span, and a tertiary heating span of a fixing rotator, respectively. A primary temperature detector and a secondary temperature detector detect a temperature of the fixing rotator. A tertiary temperature detector detects a temperature of a pressure rotator. A controller selectively performs a primary control mode to de-energize the tertiary heater and a secondary control mode to connect the secondary heater and the tertiary heater in series to energize the primary heater, the secondary heater, and the tertiary heater. The controller energizes the secondary heater and the tertiary heater in the secondary control mode based on the temperature of the fixing rotator and the pressure rotator detected by the secondary temperature detector and the tertiary temperature detector, respectively.

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.

The nip formation assembly includes a pressure pad made of heat-resistant resin including a hollow filler, and a supplementary thermal conductor having a belt sliding-contact face over which the inner circumferential surface of the endless belt slides. The supplementary thermal conductor is interposed between the endless belt and the pressure pad to conduct heat from the heater in an axial direction of the endless belt. The fixing device further includes a pressure rotator to press against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the pressure rotator, through which a recording medium bearing a toner image is conveyed.
