摘要： A heating device includes a rotator, a heater, a rotator holder, lubricant, and a shield. The heater heats the rotator in a heat generation range. The rotator holder holds an end of the rotator in a longitudinal direction of the rotator. The lubricant adheres to the rotator holder. The shield shields heat transferred from the heater. The shield includes a first shield, a second shield, and a heat transfer reducer. The first shield faces the heater and the rotator. The second shield faces the rotator holder. The second shield is outside the heat generation range in the longitudinal direction. The heat transfer reducer is disposed between the first shield and the second shield. The heat transfer reducer reduces the heat transferred from the first shield to the second shield.

摘要： A heating device includes a rotator that rotates and a heater that is disposed opposite an inner circumferential face of the rotator. The heater heats the rotator. A rotator holder is disposed opposite the inner circumferential face of the rotator. The rotator holder holds a lateral end of the rotator in a longitudinal direction of the rotator. The rotator holder is adhered with a lubricating substance. A heat shield is disposed between the heater and the rotator and between the heater and the rotator holder. The heat shield blocks radiant heat radiated from the heater and is separated from the rotator holder. The heat shield includes a first portion and a second portion that is disposed outboard from the first portion in the longitudinal direction of the rotator. The second portion is separated from the inner circumferential face of the rotator farther than the first portion is.

摘要： A fixing device includes a rotator, a heater, a rotator support, a nip formation pad, lubricant, and a pressure rotator. The heater heats an inner circumferential surface of the rotator. The rotator support supports an end of the inner circumferential surface of the rotator in an axial direction of the rotator. The rotator slides on the rotator support. The nip formation pad is in contact with the inner circumferential surface of the rotator. One end of the nip formation pad in a longitudinal direction of the nip formation pad is separated from the rotator support with a clearance of 2 mm or more. The lubricant is between the rotator and the nip formation pad. The pressure rotator presses the nip formation pad via the rotator to form a nip between the rotator and the pressure rotator.

The heater includes an elongated substrate extending in an axial direction of the first rotator, a heat generator disposed on a surface of the substrate facing the first rotator, at a position downstream in a rotational direction of the first rotator, a plurality of first conduction paths connected to the heat generator and grounded downstream of the heat generator in the rotational direction of the first rotator, and a second conduction path on which the plurality of first conduction paths are grounded. The heat generator has a heat-generating area divided into a plurality of sub-heat-generating areas in the axial direction of the first rotator. The plurality of sub-heat-generating areas are grounded on the second conduction path via the plurality of first conduction paths.
