    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 device for fixing an image formed on a recording material in an image forming apparatus includes a fixing member, a heating part that heats the fixing member to fix an image formed on the recording material by heat, a storage unit that is charged by an external power source to supply power to the heating part, and a control unit that controls the external power source to supply power to the heating part and determines whether to start to supply power to the heating part from the storage unit. The control unit controls the external power source to charge the storage unit during a period from when power supply from the storage unit to the heating part is completed at the time of warming-up the fixing member by the heating part until when the power supply from the storage unit to the heating part is started.

    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.
