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 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 fixing device includes a rotator, a secured member, a pressure rotator, and lubricant. The rotator has flexibility and a sleeve form. The rotator includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is disposed inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator is to slide. The slide surface has a smaller surface roughness in a sliding direction of the rotator than a surface roughness of the sliding surface in the sliding direction of the rotator. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant is provided between the rotator and the secured member.

摘要： A belt device includes a secured member, a belt, a pressure rotator, and lubricant. The belt has an endless shape and slides on a slide surface of the secured member. The belt has an inner portion having an elastic power of 55% or more and a sliding surface sliding on the slide surface of the secured member. The sliding surface has a surface roughness smaller than a surface roughness of the slide surface of the secured member. The pressure rotator presses the secured member via the belt to form a nip between the belt and the pressure rotator. The lubricant is interposed between the sliding surface of the belt and the slide surface of the secured member.

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.
