摘要： An image forming apparatus includes a fixing device disposed downstream from an image forming device in a recording medium conveyance direction to fix a toner image formed by the image forming device on a recording medium. The fixing device includes a pressing rotary body separatably pressed against a fixing rotary body to form a nip therebetween through which the recording medium bearing the toner image passes, and a moving assembly to move the pressing rotary body bidirectionally to press the pressing rotary body against the fixing rotary body and separate the pressing rotary body from the fixing rotary body. A controller controls the moving assembly to change a post-fixing pressing time period for which the moving assembly presses the pressing rotary body against the fixing rotary body after the recording medium bearing the toner image is discharged from the nip according to image data.

摘要： A fixing device includes a fixing rotator to fix an unfixed image on a recording medium, a pressure member disposed opposite the fixing rotator to press an outer circumferential surface of the fixing rotator; a heating source disposed inside an inner circumferential surface of the fixing rotator to heat the fixing rotator, and a composite member disposed inside the inner circumferential surface. The composite member includes a first member, a second member attached to the first member, and an inspection region for measurement of glossiness. The first member and the second member have a difference in glossiness. The inspection region allows identification of which one of the first member and the second member is present on a surface of the inspection region based on the glossiness of the inspection region, and determination of that the fixing device has a desired fixing configuration based on a result of the identification.

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.
