を備える。A roller fixing device passes an image support material between a pair of pressure rollers and fixes unfixed toner on the image support material using heat and pressure. This results in an offset phenomenon in which some parts are attached to the surface. In order to reduce the offset phenomenon, the fixing roller is provided with a means for applying a release agent (for example, silicone oil), and a fixing roller cleaning means is provided to remove offset toner.

■は装置が大がかりになること、コストが高いこと。Conventionally, the means for cleaning the roller fixing device and the means for applying a release agent are: ■ A web impregnated with silicone oil is brought into contact with the fixing roller and sent...High-speed machine @ Applying a release agent (e.g. Fluorobor) to the surface of the fixing roller There are medium-speed machines equipped with a device that presses the blade against the roller busbar to scrape off the offset toner, and low-speed machines that press cleaning felt impregnated with silicone oil against the fixing roller. . The disadvantage of these devices is that they are large-scale and expensive.
＠はコンパクトにはなるが、フロロボア及び耐熱性ブレ
ードを用いることでコストが高いこと。@ is more compact, but the cost is high due to the use of fluorobore and heat-resistant blades.
■はコストは安いがフェルトに汚れがたまるため数十枚

されている。FIG. 1 is a side view of an embodiment of the invention. The reference numeral / designates a fixing device, and a fixing roller and a pressure roller 3 are pivotally attached to frames // on both sides of the fixing device so as to rotate in pressure contact with each other. 1 is an entrance guide for the image support material, and S is a separation claw. Reference numeral 6 denotes a cleaning member in which felt 7 is wrapped around a hexagonal shaft. The felt 7 was impregnated with 10,000 ape of silicone oil (3) as a mold release agent at a ratio of 1, □ wt% to the weight of the felt. The shaft g is fitted into the notch l in the frame // on both sides, and the winding spring /S is fitted into the shaft /3 so as to be held down by a lever /s pivoted to the frame /l by the shaft 13. Both ends of the spring /S are locked to the frame // and the lever /F, respectively.
切込み／２の幅は軸ｇの外周に接する円の直径よりわず

全５ｉ４ｔローラコに圧しフェルト７は新しい面に更新
することができる。A rotary knob is attached to the front side of the cleaning member 6, and a number N is attached corresponding to each side of the felt 7. If the number of copies has increased and the felt surface becomes dirty, turn the rotary knob 9 to compress the corner of the felt grip and raise the shaft g to move the lever /4' against the spring /51'. 13 in the counterclockwise direction, and when it passes over the corner of the felt 7, the flat part of the felt 7 comes into contact with the surface of the fixing roller, and the lever/da is released by the spring l! II) The felt 7 can be renewed to a new surface by rotating clockwise with the force of 2) and pressing it against all 5i4t rollers through the shaft g.

すことができた。またフェルト面の更新は回転ノブヲを
回すだけであるのでオペレーターでも簡単に操作するこ
とが可能となった。When we looked at the durability of the cleaning felt using a regular flat felt, we found that the felt had to be replaced after 5,000 to 10,000 copies were made, but by using this hexagonal felt, the time to replace the felt can be reduced. We were able to increase the number of copies to 30,000 to 60,000. Additionally, the felt surface can be updated simply by turning the rotary knob, making it easy for operators to operate.
本実施例ではフェルトの形状を６角形としたが、６角形
に限定されるものではなく多角形であれば良い。従って
回転ノブ９も６角形の必要はなく多角形成は円形であっ
てもよいことはいうまでもない。またフェルトの形状は
第３図に示す如く各面は平面ではなく定着ローラコの曲
面に合わせて曲面にして定着ローラコとの接触幅を確実
に稼ぐことも可能である。Although the shape of the felt is hexagonal in this embodiment, it is not limited to a hexagonal shape and may be any polygonal shape. Therefore, it goes without saying that the rotary knob 9 does not have to be hexagonal and the polygon may be circular. Further, as shown in FIG. 3, each surface of the felt may be curved to match the curved surface of the fixing roller instead of being flat to securely widen the contact width with the fixing roller.

着ローラコに圧接する。To replace the felt, rotate the lever /4' counterclockwise against the winding spring 15 to open the upper part of the axis g of the notch /2, pull out the cleaning member 6 upwards, and clean it with a new felt 7. In the same way, leave the upper part of the notch 7.2 open for the member 6, and fit the shaft g into the notch.
When the lever IQ is released, the lever /
4 rotates clockwise to press the felt 7 against the fixing roller via the shaft g.

どのサービスフリーの機械では特に効果がある。As explained above, by making the cleaning felt of the fixing roller polygonal, it is possible to keep costs low with a simple device that does not require a large space, and moreover, it is possible to increase the number of durable sheets. Furthermore, it is easy to update and replace the felt surface, and users can easily operate it.
This is particularly effective for service-free machines, such as so-called personal copiers, which individuals have at hand.
