    摘要： A fixing device includes a fixing rotator and an opposed rotator pressed against the fixing rotator to form a fixing nip therebetween. A primary heater is disposed opposite the fixing rotator in a circumferential span of the fixing rotator other than the fixing nip in a circumferential direction of the fixing rotator to heat the fixing rotator. A heat shield is interposed between the primary heater and the fixing rotator and disposed outboard from at least a decreased size recording medium conveyance span of the fixing rotator spanning in an axial direction of the fixing rotator where a recording medium having a decreased size in the axial direction of the fixing rotator is conveyed. The heat shield shields the fixing rotator from the primary heater. A secondary heater is mounted on the heat shield to heat the fixing rotator.

    摘要： A fixing device for fixing an image formed on a recording material includes a fixing member and a pressing member which are rotatable to pass the recording material having an image through their nip part, a heating part that heats the fixing member, 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 and the storage unit to supply power to the heating part without rotating the fixing member and pressing member at a time of warming-up the fixing member by the heating part in a first case. The control unit further controls the external power source to supply power to the heating part and controls the storage unit so as not to supply power to the heating part while rotating the fixing member and the pressing member in a second case.

    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.
