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 heater including a heat generator that generates heat as the heat generator is supplied with power. A feeding member contacts the heater and feeds the power to the heat generator. An endless belt rotates and is heated by the heater. A driving roller contacts an outer circumferential surface of the endless belt. A driving force transmitter is disposed at one lateral end of the driving roller in an axial direction of the driving roller. The driving force transmitter transmits a driving force that drives and rotates the driving roller. The feeding member is made of a corson copper alloy and is disposed in a non-driving side defined by a center of the heat generator in a longitudinal direction of the heater. The non-driving side is opposite a driving side in the longitudinal direction of the heater, where the driving force transmitter is disposed.

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 fixing device includes a fixing belt formed into a loop rotatable in a predetermined direction of rotation and a pressure roller disposed opposite the fixing belt. The pressure roller includes a shaft fixedly positioned and a deformable elastic layer. A fixing pad is disposed inside the loop formed by the fixing belt and separably pressed against the pressure roller via the fixing belt to form a fixing nip between the fixing belt and the pressure roller, through which a recording medium bearing a toner image is conveyed. A biasing member biases the fixing pad and the fixing belt against the pressure roller. A stopper restricts motion of the fixing pad biased by the biasing member. The stopper contacts the fixing pad while the recording medium bearing the toner image is conveyed through the fixing nip.

摘要： A belt device includes a support and a support roller that support a belt. A driven gear is mounted on one of a plurality of shafts of the support roller. A driving gear meshing with the driven gear at a mesh position transmits a driving force to the support roller through the driven gear to rotate the support roller. An elastic bearing rotatably bearing each of the plurality of shafts of the support roller has an inner diameter smaller than an outer diameter of the shaft of the support roller. The bearing includes a slit defining a part of the bearing in a circumferential direction thereof. The slit is disposed upstream from the mesh position in the direction of rotation of the support roller such that the mesh position and the slit define a circumferential angle not smaller than about 20 degrees.
