【発明の名称】加熱装置及び画像形成装置 Patent application title: HEATING APPARATUS AND IMAGE FORMING APPARATUS
【０００１】
【発明の属する技術分野】
この発明は、例えば電子写真方式を使用した複写機やプリンタ装置，ファクシミリ装置等の画像形成装置のトナー像を記録用紙等に定着する定着装置等の加熱装置及び画像形成装置、特に省電力の効率化に関するものである。[0001]
Field of the Invention
The present invention relates to a heating device such as a fixing device for fixing a toner image of an image forming apparatus such as a copying machine, a printer, or a facsimile apparatus using an electrophotographic method on a recording sheet etc. Related to
【０００８】
この発明かかかる短所を改善し、省電力効果を高めるとともに立上り時間を短縮することができる加熱装置及び画像形成装置を提供することを目的とするものである。[0008]
An object of the present invention is to provide a heating apparatus and an image forming apparatus capable of improving the power saving effect and shortening the rise time while improving the above-mentioned disadvantages.
【０００９】
【課題を解決するための手段】
この発明に係る加熱装置は、加熱部と主電源装置と補助電源装置とを有し、加熱部は発熱体を有し、主電源装置と補助電源装置から供給される電力により発熱する加熱装置や、加熱部と、主電源装置により充電される補助電源装置とを有し、加熱部は発熱体を有し補助電源装置から供給される電力により発熱する加熱装置において、補助電源装置としてコンデンサを用いることを特徴とする。この補助電源装置としてコンデンサを用いると良い。また、コンデンサは、電気二重層コンデンサであることが望ましい。 [0009]
[Means for Solving the Problems]
A heating device according to the present invention includes a heating unit, a main power supply device, and an auxiliary power supply device, the heating unit includes a heating element, and generates heat by electric power supplied from the main power supply device and the auxiliary power supply device. A heating unit and an auxiliary power supply charged by the main power supply, wherein the heating unit has a heating element, and generates heat using electric power supplied from the auxiliary power supply, wherein a capacitor is used as the auxiliary power supply It is characterized by It is preferable to use a capacitor as this auxiliary power supply device. Also, the capacitor is preferably an electric double layer capacitor.
【００１０】
上記加熱部はトナー像を加熱して定着する画像形成装置の定着装置である。また、加熱部はハロゲンヒータを有し、主電源装置から電力の供給を開始してからタイミングをおいて補助電源装置から電力を供給したり、補助電源装置から加熱部に対する電力投入を、主電源装置から加熱部に対する電力投入より早くして、加熱部に電力を投入するときの投入電流を小さくすることが望ましい。 [0010]
The heating unit is a fixing device of an image forming apparatus that heats and fixes a toner image. In addition, the heating unit has a halogen heater, and the auxiliary power supply unit supplies power from the main power supply unit at a timing after power supply is started, or the auxiliary power supply unit supplies power to the heating unit from the main power supply unit. It is desirable to reduce the input current when power is supplied to the heating unit earlier than power being supplied from the device to the heating unit.
【００２２】
さらに、加熱部に電力を供給するとき、主電源装置から電力投入と補充電源装置からの電力投入のタイミングをずらすことにより、加熱部のヒータに対する投入電流を小さくしてヒータ寿命が短くなる等の障害を防ぐことができ、安定して長期間使用することができる。 [0022]
Furthermore, when power is supplied to the heating unit, the input current to the heater of the heating unit is reduced by shifting the timing of power supply from the main power supply device and power supply from the supplementary power supply device to shorten the life of the heater. Failure can be prevented and stable and can be used for a long time.
