    摘要： A fixing device includes a fixing rotator formed into a loop and rotatable in a predetermined direction of rotation and a pressure rotator disposed outside the loop formed by the fixing rotator and pressed against the fixing rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A stay is disposed opposite the pressure rotator via the fixing rotator. A heater is disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. A pressurization member is pressed against the heater via the fixing rotator. A housing is interposed between the stay and the heater. A temperature detector is mounted on the housing to detect a temperature of the heater.

    摘要： A fixing device includes a fixing member, a pressing member, a heating unit, multiple sub-heaters disposed in the heating unit, a temperature sensor to detect a temperature of the heating unit, and a heating control unit. The heating control unit controls the heating unit by controlling the multiple sub-heaters individually to heat the respective heating areas, such that a temperature at a portion of the fixing member corresponding to a blank area of the recording medium is lower than a temperature of a portion of the fixing member corresponding to an imaged area of the recording medium. The heating control unit further changes a size of a preliminary heating area to preliminarily heat the respective heating areas before the imaged area enters the fixing nip according to the temperature detected by the temperature sensor.

    摘要： A fixing device includes a rotatable, endless fixing belt; a rotatable contact member configured to contact a circumferential surface of the fixing belt to form a nip in association with the fixing belt; and a heating member disposed at an interior surface of the fixing belt, configured to heat the fixing belt. The heating member includes a multiple heat sources arranged along the width of a sheet of recording media in a direction perpendicular to a sheet conveyance direction. A controller changes an area to be heated by each heat source based on image data and corresponding to an unfixed image on the sheet. The fixing belt is heated by the heating member so that the unfixed image on the sheet that has been conveyed to the nip is fixed onto the sheet at least with heat. The heating member is disposed at a portion other than the fixing nip.

    摘要： An image forming apparatus includes a main power unit that outputs a first DC power and an auxiliary power unit that outputs a second DC power to the components of the image forming apparatus. The auxiliary power unit includes a rechargeable capacitor. A measuring unit measures performance of the capacitor and a determining unit determines performance insufficiency of the capacitor based on the measured performance and the system configuration of the image forming apparatus. The performance is, for example, changes in a capacitance of the capacitor with time. When the determining unit determines performance insufficiency of the capacitor, a control unit adjusts, for example, a use range of the capacitor.

    摘要： A power supply device includes a first power-supply unit to input external power and to output first power supplying a predetermined constant voltage to a load, a second power-supply unit to accumulate charge and to output second power to the load in parallel with the first power being supplied from the first power-supply unit, and a controller to output a control signal to prevent the second power-supply unit from supplying power in case of a current increase due to a dynamic load change, and to cause the first power-supply unit to supply power for the dynamic current increase. The first power-supply unit supplies power having a current value smaller than a predetermined maximum current of the first power-supply unit. The second power-supply unit supplies power for a shortfall current exceeding the predetermined maximum current of the first power-supply unit.
