程度の電力を供給して余分なエネルギを消費していた。In recent years, environmental problems have become important, and energy saving has also been progressing in image forming apparatuses such as copiers and printers. In considering the energy saving of the image forming apparatus, what cannot be ignored is the power saving of the fixing device that fixes the toner on the recording medium. In order to reduce the power consumption of the fixing device during standby of the image forming apparatus, the temperature of the heating roller is maintained at a fixed temperature slightly lower than the fixing temperature during standby, so that the temperature immediately rises to the usable temperature at the time of use, and the user can use the device. It does not wait for the temperature of the fixing roller to rise. In this case, even when the fixing device is not used, a certain amount of power is supplied to consume extra energy.

ルギーが電源により決まってしまっていた。[0004] It is desired to reduce the energy consumption during standby to achieve more power saving, and it is required to reduce the power supply to zero when not in use. However, if the energy consumption is reduced to zero during standby, the heating roller mainly uses a metal roller such as iron or aluminum and has a large heat capacity, so that it takes several minutes to 10 minutes to raise the temperature to a usable temperature of about 180 ° C. A long heating time such as several minutes is required,
The usability of the user is deteriorated. In order to shorten the heating time of the heating roller, it is preferable to increase the input energy per unit time, that is, the rated power. In fact, many high-speed machines with a high printing speed are compatible with a power supply voltage of 200 V. However, in a general office in Japan, the commercial power supply is 100 V and 15 A. In order to cope with 200 V, it is necessary to perform special work on the power supply at the installation location, and this is not a general solution. For this reason, even if an attempt is made to raise the temperature of the heating roller in a short time, the maximum input energy has been determined by the power supply.

The fixing device disclosed in Japanese Patent Application Laid-Open No. 0-10913 supplies a low voltage to the fixing device by a certain level even in the standby state, and therefore cannot be said to have sufficient power saving. Further, the present invention does not mainly focus on increasing the maximum supply power at the time of startup than the power supplied from the main power supply device. JP-A-10-2828
The fixing device disclosed in Japanese Patent No. 21 supplies power from a main power supply device and a secondary battery or a primary battery at the time of startup.
Generally, CADNICA batteries and lead-acid batteries are used as the secondary power supply. Have. In general, even a CADNICA battery which is considered to have a long life at a large current has a repetition rate of about 50 times.
It is about 0 times, and if the charge / discharge is repeated 20 times a day, the battery life will end in about 1 month, it takes time to replace, and the running cost of replacing the battery is very high. There is a disadvantage that it can be turned on. Furthermore, lead storage batteries are not preferred as office equipment, such as those using liquid sulfuric acid.

Although it depends on the impedance of the power supply, the rated current is 7 to 10
A current nearly twice as large may flow. As can be seen from the data that the life decreases by 80% when the current increases by 10%, it is not preferable that an excessive current flows through the heater even at an instant. Also, a rush current flows in the peripheral circuit in the same manner, so that there is a concern that adverse effects may occur, and special measures may need to be taken.

In the case where a halogen heater is used for the heater 6, as shown in the waveform diagram of FIG. 2 to supply electric power from the auxiliary power supply 4 to the heating unit 2. That is, in the halogen heater, a rush current is generated when the power is turned on due to its characteristics, which affects the circuit damage and the life of the heater itself. When the power of the auxiliary power supply 4 is also supplied to the halogen heater at the same time as the power supply of the main power supply 3, the rush current of the halogen heater increases, and there is a fear that the life of the halogen heater or the like may be shortened or the circuit may be adversely affected. It needs to be applied. On the other hand, by supplying power from the auxiliary power supply 4 to the heating unit 2 at a certain timing T after the supply of power from the main power supply 3 to the heating unit 2 is started, the input current of the halogen heater is reduced. In addition, problems such as shortened heater life are prevented. The power supply from the auxiliary power supply 4 may be earlier than the power supply from the main power supply 3 by a certain timing.
