    摘要： A heating device includes an endless rotator that rotates in a rotation direction and a heater that contacts an inner circumferential surface of the endless rotator and extends in an axial direction of the endless rotator. An elastic body contacts the inner circumferential surface of the endless rotator and is disposed downstream from the heater in the rotation direction of the endless rotator. A holder holds the heater and the elastic body. A pressure rotator is disposed opposite the heater and the elastic body via the endless rotator to form a nip between the endless rotator and the pressure rotator. A motion restrictor is mounted on the holder. The motion restrictor restricts motion of the heater downstream in the rotation direction of the endless rotator.

    摘要： A heating device includes a belt that rotates in a rotation direction and has a temperature decrease span in an axial direction of the belt, where the belt is susceptible to temperature decrease. A resistive heat generator is disposed opposite the belt. The resistive heat generator heats the belt and extends in the axial direction of the belt. The resistive heat generator includes a primary heat generating portion that generates heat in a first heat generation amount and a secondary heat generating portion that is disposed outside the primary heat generating portion and disposed opposite the temperature decrease span of the belt. The secondary heat generating portion generates heat in a second heat generation amount that is greater than the first heat generation amount of the primary heat generating portion.

    摘要： A fixing device includes a heater including a heat generator that is divided into a plurality of heat generating portions in an axial direction of the endless belt. The heat generator defines a dividing region between adjacent ones of the plurality of heat generating portions and a non-dividing region other than the dividing region. A primary guide contacts and guides the endless belt. The primary guide is disposed opposite the dividing region of the heat generator and has a first thermal capacity. A secondary guide contacts and guides the endless belt. The secondary guide is disposed opposite the non-dividing region of the heat generator and has a second thermal capacity that is greater than the first thermal capacity.

    摘要： An image forming apparatus includes a heating device including a heat generator and a resistance value identifier, a body, a resistance value acquisition unit, a detector to detect detachment and attachment of the heating device from and to the body, and an electric power controller. The resistance value identifier corresponds to a resistance value of the heat generator. The resistance value acquisition unit acquires the resistance value from the resistance value identifier. The electric power controller causes the resistance value acquisition unit to acquire the resistance value when the detector detects detachment and attachment of the heating device. The electric power controller changes a lighting duty of the heat generator when the acquired resistance value of the heat generator is different from the resistance value before the detector detects detachment and attachment of the heating device.

    摘要： An image forming apparatus includes a power controller that starts an examination mode by an external operation. The examination mode detects a temperature-resistance property of a resistive heat generator. The power controller supplies power at a predetermined power duty cycle to the resistive heat generator. The power controller obtains the power supplied to the resistive heat generator and a change in a temperature of the resistive heat generator, that is detected by a temperature detector, while the power controller supplies the power at the predetermined power duty cycle to the resistive heat generator. The power controller calculates the temperature-resistance property of the resistive heat generator based on the power and the change in the temperature that are obtained. The power controller adjusts a power duty cycle at which the power is supplied to the resistive heat generator based on the temperature-resistance property.

    摘要： A disclosed fixing device includes a fixing material application unit applying a fixing material to a fixing material carrier, a transfer unit transferring the fixing material onto a recording medium, a cleaning blade cleaning the fixing material carrier after the fixing material is transferred onto the recording medium, and a lubricant agent application unit disposed on a downstream side of the cleaning blade on the fixing material carrier and applying a lubricant agent to the fixing material carrier. Further, before a fixing operation is started, the lubricant agent application unit applies the lubricant agent to the fixing material carrier, and the fixing material carrier moves in a direction opposite to a direction when the fixing operation is performed and to a position where the applied lubricant agent is adhered to the cleaning blade.
