摘要： A fixing device includes at least one temperature detector and a device-side connector. The at least one temperature detector is configured to detect a temperature of the fixing device. The device-side connector is configured to transmit a temperature detection signal from the at least one temperature detector to an image forming apparatus body by mutual contact between a terminal of the device-side connector and a terminal of a body-side connector of the image forming apparatus body. A lead wire of the at least one temperature detector is branched into a plurality of wires connected to the device-side connector.

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.

The fixing device includes a fixing rotator having a fixing surface, an opposing rotator opposing the fixing rotator to form a nip portion therebetween, and a fixing surface reformer having an abutting layer to abut the fixing surface. The abutting layer contains abrasive grains having an average grain size of 2.0-6.5 μm on a surface which abuts the fixing surface. The toner comprises a crystalline polyester resin and exhibits G′ (storage elastic modulus) of 1.0×107 Pa or lower at 70° C. in a temperature rising in a viscoelasticity measurement, G′ of 1.0×107 Pa or higher at 70° C. in a temperature falling in the viscoelasticity measurement, and an endothermic peak indicating an amount of heat absorption of from 2.0 to 8.0 J/g, derived from the crystalline polyester resin, in a first temperature rising in DSC.

摘要： A fixing device includes an endless, rotatable fixing belt, a pressure rotator, a nip formation pad, a support, and a vibration repressor. The pressure rotator presses an outer surface of the fixing belt. The nip formation pad is disposed at an inner side of the fixing belt, to abut on the pressure rotator with the fixing belt interposed between the nip formation pad and the pressure rotator to form a fixing nip. The support is disposed at the inner side of the fixing belt, to support the nip formation pad. The vibration repressor is disposed between the nip formation pad and the support, to repress vibration of the nip formation pad.

摘要： A controller for a vehicle transmission is disclosed. The controller may include an electronic control unit configured to carry out a change shift for changing a path of the transmission of power between a first transmission path and a second transmission path by engaging a predetermined clutch mechanism. The electronic control unit may also be configured to set a change speed ratio region that defines a range of a speed ratio of the first transmission mechanism such that a rotation speed difference between engagement members of the clutch mechanism, which are engaged with each other in carrying out the change shift, is smaller than or equal to a predetermined value. When a speed ratio outside the change speed ratio region is set in the first transmission mechanism, the change shift is not carried out.
