摘要： A fixing member, a power detector, and a controller are included. The fixing member is heated by a heating unit that generates heat when power is supplied by a commercial power and a capacitor. The power detector detects energy of power stored in the capacitor. The controller performs an identical control to reduce number of copies of an image formed (fixed) per minute (CPM) to a predetermined number (40 CPM) in any of three cases in which the energy is less than a threshold for starting electric discharge when a plurality of recording mediums is continuously passed through the fixing member, in which a cardboard paper is continuously passed, and in which an amount of data of an image to be transferred on the recording medium is large.

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.

摘要： A fixing apparatus includes an electrical condenser charged by a commercial power source, a heat generating member that generates heat when the electrical condenser supplies power, and a fixing device that is heated by the heat generating member and fixes an image onto a recording medium. A temperature switch is activated when temperature of the fixing member reaches a prescribed abnormal level. A power supply circuit is provided to convey the power from the electrical condenser to the heat generating member. A cutting off device is provided to cut off the power supply circuit when the temperature switch is operated.

摘要： A fixing device for fixing an image formed on a recording material includes a fixing member disposed on a recording material conveyance path, a heating part that heats the fixing member to fix the image formed on the recording material by heat, and a storage unit that is charged by an external power source to supply power to the heating part. The fixing device further includes a fixing temperature detecting unit that detects a temperature of the fixing member, and a control unit that controls the external power source to supply power to the heating part and to determine whether to start to supply power to the heating part from the storage unit based on the temperature of the fixing member, at the time of warming-up the fixing member by the heating part.
