摘要： An image forming apparatus includes a resistive heat generator, a temperature detector, and a power controller that detects a temperature-resistance property of the resistive heat generator before the resistive heat generator is used when the resistive heat generator is removably installed. The power controller obtains power supplied to the resistive heat generator and a change in a temperature of the resistive heat generator, that is detected by the temperature detector, while the power controller supplies the power at a predetermined power duty cycle for adjustment 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 in use of the resistive heat generator, based on the temperature-resistance property.

摘要： A heating device includes a base, resistance heating elements, a power control circuit, a first temperature detector, a second temperature detector, a power interrupter, and control circuitry. The resistance heating elements are arranged in a longitudinal direction of the base and electrically connected in parallel. The first detector detects a temperature of a first resistance heating element. The second detector detects a temperature of a second resistance heating element. The power interrupter interrupts power supplied to the resistance heating elements when the temperature of the second resistance heating element becomes a predetermined temperature or more. The control circuitry controls the circuit such that a temperature of each resistance heating element becomes a predetermined temperature, based on a result of detection of the first detector, and interrupts the power supplied to the resistance heating elements when the second detector detects predetermined temperature information regarding the second resistance heating element.

摘要： A heater includes a base and at least one resistive heat generator mounted on a face of the base. At least one electrode supplies power to the at least one resistive heat generator. A conductor couples the at least one electrode with the at least one resistive heat generator. A slide layer covers the at least one resistive heat generator and the conductor. The slide layer includes a projecting portion that defines a surface of the slide layer. The projecting portion is defined by a film thickness of at least one of the conductor and the at least one resistive heat generator. The projecting portion includes an upstream projection disposed opposite a lateral end of the base in a longitudinal direction of the base and a downstream projection disposed downstream from the upstream projection in a rotation direction of an endless belt that slides over the heater.

摘要： A heating device includes an endless rotator that rotates in a rotation direction. A heater contacts the endless rotator. An elastic body is disposed opposite an inner circumferential surface of the endless rotator and 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 slide sheet covers a surface of the elastic body. The slide sheet includes an upstream end in the rotation direction of the endless rotator. The upstream end is sandwiched between the heater and the elastic body and between the elastic body and the holder. The upstream end is secured to the holder.
