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 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 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 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： An image forming apparatus includes a thermal fixing unit having a fixing member heated or cooled at multiple levels of the target fixing temperature in accordance with prescribed different image formation conditions, and a pressing member pressing against the fixing member to form a fixing nip thereon. A controller is provided to permit an image formation device to start image formation when temperature of the fixing member decreases to a level equal to or less than a prescribed image formation permissible temperature from temperature higher than one of the multiple levels of the target fixing temperature. The prescribed image formation permissible temperature is calculated by adding a prescribed adjustment value determined in accordance with a type of an image to be outputted to one of the multiple levels of the target fixing temperature.
