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

摘要： An image forming apparatus includes a heating device, a recording medium ejector, a recording medium tray, an outer wall having an intake, and a filter. The heating device heats a recording medium having an image on one side of the recording medium. The recording medium ejector ejects the recording medium with the one side facing downward. On the recording medium tray, the recording medium ejected by the recording medium ejector is stacked. The intake is open toward the recording medium tray and is disposed at a position below the recording medium ejector. At the position, a maximum amount of recording media placeable on the recording medium tray does not cover at least a part of the intake. The filter collects foreign substances in air sucked from the intake.

摘要： A heating device includes a rotator, a heater, lubricant applied to the rotator, a rotator support, and a cover. The rotator has an internal space inside a loop of the rotator. The heater heats the rotator. The lubricant is applied to an inner circumferential surface of the rotator. The rotator support supports an end of the rotator in a longitudinal direction of the rotator and has an opening communicating with the internal space of the rotator and penetrating through the rotator support to extend in the longitudinal direction. The cover covers the opening of the rotator support.

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 heater includes a base, a plurality of heat generators arranged on the base in parallel to a longitudinal direction of the base, a plurality of electrodes on the base, and conductor paths disposed on the base. The conductor paths are electrically connected to the heat generators and the electrodes. The conductor paths include a main conductor path connected to one of the electrodes and a branch conductor path branched from the main conductor path. At least a part of the branch conductor path has a lower electrical resistance per unit length than an electrical resistance per unit length of the main conductor path.
