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 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 heating device includes a rotator, a heating source, a rotator holder, and a liquid or semi-solid substance. The rotator is rotatably held. The heating source heats the rotator. The rotator holder holds a longitudinal end portion of the rotator. The rotator holder includes a reflector disposed at least at a portion to be irradiated with radiant heat emitted from the heating source to reflect the radiant heat. The reflector has a reflectance of not less than 60%. The liquid or semi-solid substance has lubricity and adheres to the rotator holder.

摘要： A heating device includes a rotating body, a heating source, a rotating body holder, and a lubricant of liquid or semi-solid. The heating source heats the rotating body. The rotating body holder holds both longitudinal ends of the rotating body rotatably. The lubricant of liquid or semi-solid adheres to the rotating body holder. A temperature of the rotating body holder is lower than a generation temperature of fine particles of the lubricant.

摘要： A heating device includes a rotator, a heating source, a reflector, a shield, a rotator holder, and a liquid or semi-solid substance. The rotator is rotatably held. The heating source heats the rotator. The reflector reflects radiant heat emitted from the heating source. The shield is disposed closer to a longitudinal end portion of the rotator than to a longitudinal center portion of the rotator to shield, between the heating source and the rotator, the radiant heat emitted from the heating source. The shield has a reflectance lower than a reflectance of the reflector. The rotator holder holds the longitudinal end portion of the rotator. The liquid or semi-solid substance has lubricity and adheres to the rotator holder.

摘要： A fixing device for fixing an unfixed image onto a recording medium includes a fixing belt, a nip forming member, an opposing rotary member, a heater, and a temperature detector. The fixing belt is formed into a loop to move endlessly and fix the unfixed image on the recording medium. The nip forming member is disposed inside the loop formed by the fixing belt. The opposing rotary member contacts the nip forming member via the fixing belt to form a nip portion therebetween while rotating. The heater heats the fixing belt at a place other than the nip portion. The temperature detector detects a temperature of the surface of the fixing belt. The temperature detector detects the temperature near a place of the fixing belt that easily deforms as the fixing belt is heated by the heater.
