［発明の目的］
（産業上の利用分野）
この発明は、転写ベルトを含んだ電子複写機等
の画像形成装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image forming apparatus such as an electronic copying machine that includes a transfer belt.
（従来の技術）
ローラ間に掛渡され無端走行するベルトは走行
中に片寄りし、これが原因で蛇行することがあ
る。これはローラの径やわずかな傾きによるベル
トの幅方向のテンシヨンバラツキ、ベルトの老化
による幅方向両側縁の周長のバラツキなどの原因
から生じるもので避けられないのが現状である。(Prior Art) A belt that is stretched between rollers and runs endlessly may shift to one side while running, and this may cause it to meander. At present, this is unavoidable because it arises from causes such as tension variations in the width direction of the belt due to the diameter of the roller and slight inclination, and variations in the circumferential length of both sides of the belt in the width direction due to aging of the belt.
従つて、電子複写機の転写ベルトのように複数
個のローラ間に幅広の転写ベルトを掛渡し、感光
体と転接しながら無端走行させているものにおい
ては、転写ベルトの片寄りによつて転写ベルトの
一端縁がローラの端部から外方へ外れ、他の機構
と接触して破損したり、転写ベルトの一端縁が波
打ちして皺を発生させることがあり、転写工程に
悪影響を及ぼすとともに転写ベルトの寿命を短縮
させている。 Therefore, when a wide transfer belt is stretched between multiple rollers, such as the transfer belt of an electronic copying machine, and is run endlessly while rolling in contact with the photoreceptor, the transfer is caused by the deviation of the transfer belt. One edge of the belt may come off the edge of the roller and come into contact with other mechanisms and be damaged, or one edge of the transfer belt may become wavy and wrinkle, which may have a negative impact on the transfer process. This shortens the life of the transfer belt.
これに対して、いくつかの技術が提案されてい
る。 Several techniques have been proposed for this purpose.
例えば、一般的に幅広な無端ベルトに対して
は、実公昭51―13826号公報等に示されるように、
案内ローラを用いて片寄りを規制する技術が挙げ
られる。 For example, for generally wide endless belts, as shown in Publication of Utility Model Publication No. 13826/1983,
One example is a technique that uses guide rollers to restrict deviation.
このような技術によれば、確かにベルトの片寄
りが減少し、皺の発生が減少する。 According to such a technique, it is true that the deviation of the belt is reduced and the occurrence of wrinkles is reduced.
しかしながら、上記技術は、単に幅広な無端ベ
ルトの走行を問題としているので、電子複写機等
の画像形成装置に用いられる転写ベルトに対し
て、上記技術を適用したとしてもさらに、以下の
点が問題点として残る。 However, the above technology simply deals with the running of a wide endless belt, so even if the above technology is applied to a transfer belt used in an image forming apparatus such as an electronic copying machine, the following problems still occur. It remains as a point.
すなわち、特開昭52―123627号公報に示されて
いるように、電子複写機においては転写ベルトで
記録紙を搬送させた後、記録紙を転写ベルトから
剥離させ、複写原稿を得るものである。 That is, as shown in Japanese Patent Application Laid-Open No. 123627/1983, in an electronic copying machine, a recording paper is conveyed by a transfer belt, and then the recording paper is peeled off from the transfer belt to obtain a copied original. .
よつて、上記転写ベルトでは一般の幅広な無端
ベルトと同様に、トナー像転写時には皺が発生し
ないことが必要であると同時に記録紙が、転写ベ
ルトから良好に剥離されることが必要となる。 Therefore, like a general wide endless belt, it is necessary for the above-mentioned transfer belt that wrinkles do not occur during toner image transfer, and at the same time, it is necessary that the recording paper be well peeled from the transfer belt.
しかしながら、上記公報に記載された案内板と
案内押圧板とから成る片寄り防止技術により無端
ベルトの皺の発生を防止すると、記録紙とベルト

録紙とベルトとの剥離は良好になされるかもしれ
ないが、トナー像の転写が良好に達成されず、電
子複写機等の画像形成装置の転写ベルトとしては
全く意味のないものとなつてしまつた。 However, if the generation of wrinkles in the endless belt is prevented by using the shift prevention technology described in the above-mentioned publication, which consists of a guide plate and a guide pressure plate, the adhesion between the recording paper and the belt is maintained, and the separation of the two is prevented. There is a risk of it becoming a hindrance. On the other hand, if adhesion is not maintained, that is, if wrinkles occur, the separation between the recording paper and the belt may be successful, but the transfer of the toner image will not be achieved properly, and electronic copying will fail. It has become completely meaningless as a transfer belt for image forming devices such as machines.

The purpose of this invention is to prevent the belt from shifting and also to achieve good peeling of recording paper, etc.

A transfer belt stretched between a drive roller and a guide roller, and an opening angle toward the transfer belt on both side edges of the transfer belt immediately before being wound on the winding side of the drive roller. The present invention is characterized in that it includes a regulating plate member which is provided opposite to the L-shape having an acute angle, and whose inner surfaces press downwardly against the upper surfaces of both side edges of the transfer belt.

される。 Reference numerals 96 and 96 are regulating plates that are regulating members. The regulating plates 96, 96 are installed opposite both side edges of the transfer belt 17 immediately before being wound on the winding side of the transfer belt 17 with respect to the drive roller 15. The regulating plates 96, 96 have an L-shape with an acute opening angle toward the transfer belt 17. Moreover, this regulation plate 96,9
6, the distance between the opposing parts that contact the transfer belt is set slightly narrower than the width of the transfer belt,
The inner surface thereof is adapted to press downwardly against the upper surface of both side edges of the transfer belt 17. With this configuration, the deviation of the transfer belt 17 is regulated by the regulating plates 96, 96 regardless of the thickness of the transfer belt 17.
ここで重要点は、トナーの像の転写は、感光体

規制されると、上記のように、その両端において
下方へ突然圧接される（第３図参照）。 The important point here is that the toner image is transferred between the photoreceptor 4 and the transfer belt 17, and then the belt 17 is wound around the drive roller 15. When this belt 17 is regulated by the regulating plates 96, 96, its both ends are suddenly pressed downward as described above (see FIG. 3).
よつて、これまで平面的に維持されていたベル
ト１７の表面の両端部が突然下方へ圧接されるこ
とになる。これによりベルト１７には波打ち現象
が生じる。 Therefore, both ends of the surface of the belt 17, which had been kept flat until now, are suddenly pressed downward. This causes a waving phenomenon in the belt 17.
通常この波打ち現象は、片寄りを防止した量に
比例して発生するので、通常の動作である限り、
小規模な波打ち現象が発生するだけである。 Normally, this waving phenomenon occurs in proportion to the amount of deviation prevented, so as long as it is normal operation,
Only a small rippling phenomenon occurs.

により、少なくとも両者の剥離性が向上する。 However, for the belt 17, this small-scale undulation has a large effect. That is, while the belt 17 has been conveyed to the vicinity of the regulating plates 96, 96 while remaining in close contact with the copy paper P, both ends of the belt 17 are suddenly pressed downward at the regulating plates 96, 96. As a result, the belt 17 is undulated, and the belt 17
The adhesion between the paper and the copy paper P is impaired. This improves at least the releasability of both.
このように、本実施例によれば、転写ベルト１
７上の複写紙Ｐの剥離性が向上するという効果が
ある。 In this way, according to this embodiment, the transfer belt 1
This has the effect of improving the peelability of the copy paper P on the paper 7.
