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.

摘要： A nip former that forms a nip between an endless belt and a pressure rotator includes a base that is made of aluminum and has a nip forming face disposed opposite the nip. An anodic oxidation coating is treated with sealing and coats at least the nip forming face. The anodic oxidation coating has a thickness that is not smaller than 22 μm and is not greater than 45 μm and a variation in thickness that is not greater than 20 percent. The base and the anodic oxidation coating define a nip forming portion that is disposed opposite the nip. The nip forming portion has a thickness that is not smaller than 0.40 mm and is not greater than 1.20 mm.
