    摘要: A fixing device for fixing an image formed on a recording material includes first and second rotary members having a nip part therebetween, a heating part that heats the first rotary member, a center portion temperature detecting unit that detects a temperature of a center portion of the first rotary member, and an end portion temperature detecting unit that detects a temperature of an end portion of the first rotary member. When recording materials each having a relatively large width consecutively pass through the nip part, a control unit controls a heating amount of a full width heating member based on the temperature detected by the center portion temperature detecting unit, and when recording materials each having a relatively small width consecutively pass through the nip part, the control unit controls the heating amount of the full width heating member based on the temperature detected by the end portion temperature detecting unit.

    摘要: A heating device, a fixing device and an image forming device are disclosed for making the life-span of a capacitor thereof longer. The heating device includes a heating part having at least one heat generation part generating heat, an electricity storage device supplying electric power at a variable output voltage to the heating part and having at least one chargeable-dischargeable capacitor, a control part controlling the output voltage of the electricity storage device, and a temperature detection part detecting a temperature of a portion heated by the heat generation part. The heat generation part generates heat by using electric power supplied from the electricity storage device. When the temperature detected by the temperature detection part is higher than or equal to a predefined temperature, the control part sets a voltage of the capacitor such that the voltage of the capacitor is lower than or equal to a maximum voltage of the capacitor.

    摘要: Power is supplied from a capacitor of an auxiliary power source to a secondary heating element of a heating unit, thereby preventing temperature drop of a fixing roller at the time of continuous paper delivery. An allowable range for starting discharge from the capacitor is set to, for example, 30 to 40 volts. A discharge time in which the voltage of the capacitor reduces to a termination value, such as 20 volts, is longer than a time necessary for a reading unit to read a maximum number (for example, 100 sheets) of documents that can be read at one time.

    摘要: A fixing unit thermally fixes a toner on a recording medium by a fixing member having a plurality of internal heaters and an outer peripheral surface, and a temperature sensor detects a surface temperature of the fixing member at a temperature detecting position. At least one first heater, of the heaters, receives power from a first power supply, and remaining second heaters receive power from a second power supply. One of the second heaters closest to the temperature detecting position is the same distance from the temperature detecting position as or is closer to the temperature detecting position than a first heater which is closest to the temperature detecting position.
