[Technical field to which the invention belongs]
The present invention is a copying machine using an electrophotographic system, heating body used in the printer over, facsimile, to a heating device and an image forming apparatus.
フィルム加熱方式の加熱装置は、加熱体として低熱容量線状加熱体を、フィルムとして薄膜の低熱容量のものを用いることが出来るため、省電力化・ウェイトタイム短縮化(クイックスタート性)が可能である。またこの種の定着方式においては、定着フィルムの駆動方式にフィルム内周面に駆動ローラを設け、フィルムにテンションを加えながら駆動する方式、フィルムをフィルムガイドにルーズに嵌合させ、加圧用回転体を駆動することで、フィルムを加圧用回転体に対し従動回転させる方式が知られているが、近年では部品点数が少なくて済むことから、後者の加圧用回転体駆動方式が採用されることが多い。 Since the film heating type heating device can use a linear heating body with a low heat capacity as the heating body and a thin film with a low heat capacity as the film, it is possible to save power and shorten the wait time (quick start property). is there. In the fixing method of this type, the driving low-La on the film in the peripheral surface on a driving mode of the fixing film is provided, a method of driving while applying tension to the film, fitted loosely to the film in the film guide, pressure rotor A method is known in which the film is driven to rotate with respect to a rotating body for pressurization by driving the body, but in recent years, since the number of parts is small, the latter method for driving the rotating body for pressurization is adopted. There are many.
回転感光ドラムD面に形成されたトナー像は、感光ドラムDと転写装置35との対向部である転写部位において、該転写部位に対して所定の制御タイミングにて給送された記録紙(転写材・被記録材)8に対して順次に転写される。転写装置35としては図に示したコロナ帯電器以外に、導電弾性回転体に電源から電流を供給して記録紙に転写電荷を付与しながら搬送する転写ローラ方式等がある。 The toner image formed on the surface of the rotating photosensitive drum D is a recording paper (transfer) fed to the transfer portion at a predetermined control timing at the transfer portion facing the photosensitive drum D and the transfer device 35. Material / recorded material) 8 is sequentially transferred. Besides corona charger shown in the figure as a transfer device 35, there is a conductive elastic rotating member transferring rows la direction by supplying a current from a power source for conveying while applying transfer charge to the recording paper type or the like.
37はプリンター内の下部に装着した給紙カセットであり、記録紙8を積載収納させてある。この給紙カセット37内の記録紙8が給紙ローラ38と分離爪部材39により1枚分離給送され、シートパス40、レジストローラ対41、シートパス42の経路で転写部位へ所定の制御タイミングにて給送される。転写部位にてトナー像の転写を受けた記録紙8は回転感光ドラムD面から順次に分離されて、像加熱装置としての定着器Rへ導入されてトナー像の定着処理(加熱加圧による永久固定画像化)を受け、シートパス43、排紙ローラ44を経由して排紙トレイ45に送り出される。 Reference numeral 37 denotes a paper feed cassette mounted at the lower part of the printer, and the recording paper 8 is loaded and stored. Predetermined recording sheet 8 of the paper feed cassette 37 is fed a low-La 3 8 and the separation pawl member 39 feed one sheet separated and fed, sheet path 40, registration straw roller pair 41, the transfer portion in the path of the sheet path 42 It is sent at the control timing of. The recording paper 8 on which the toner image is transferred at the transfer site is sequentially separated from the rotating photosensitive drum D surface and introduced into the fixing device R as an image heating device to fix the toner image (permanent by heating and pressurizing). receiving a fixed imaging), sheet path 43, is fed to the paper discharge tray 45 via the paper ejection row La 4 4.
c)加圧部材9はローラでなくともよい。例えばベルト部材にすることもできる。 c) pressing member 9 may not be low la. For example, it can be a belt member.
