Abstract
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.
