形成する感光ドラムと、その感光ドラム上の電位画像に
トナーを供給しトナー画像を作る現像器と、トナー画像
を用紙に転写させる転写帯電器と、用紙の上にトナー画
像を固定させる定着器と、用紙を移動させる搬送部とを
含んで構成される。In general, an image forming apparatus includes a head that generates image signal light, a photosensitive drum that receives light from the head and forms a potential image on its surface, and a toner that supplies toner to the potential image on the photosensitive drum. The image forming apparatus includes a developing device that forms an image, a transfer charger that transfers the toner image onto the paper, a fixing device that fixes the toner image on the paper, and a conveyance unit that moves the paper.
従来の転写帯電器は用紙の巻き込みを防止するために使
用している転写ガイドがポリアミド（ＰＡ）樹脂やポリ
エチレンテレＶタレート （ＰＥＴ）樹脂を材料とした
ものであった。In conventional transfer chargers, the transfer guide used to prevent paper from getting caught is made of polyamide (PA) resin or polyethylene tere-V-talate (PET) resin.
しかしながら、このような上述した従来の転写脂を使用
しているため、浮遊トナーを吸着して用紙の裏面にトナ
ー汚れを発生させたり、コロナ放電による電位分布を乱
し、転写不良を起こすという欠点がある。However, since the above-mentioned conventional transfer resin is used, it has the drawbacks of attracting floating toner and causing toner stains on the back side of the paper, and disturbing the potential distribution due to corona discharge, resulting in poor transfer. There is.
本発明の転写帯電器は、用紙の巻き込みを防止する転写
ガイドの材料として、浮遊トナーが付着しにくくコロナ
放電による電位分布を乱すことの少ないポリイミド（Ｐ
Ｉ）樹脂を使用して構成される。The transfer charger of the present invention uses polyimide (P) as a material for the transfer guide that prevents paper from getting caught in the paper.
I) Constructed using resin.
次に、本発明の実施例について、図面を参照して説明す
る。Next, embodiments of the present invention will be described with reference to the drawings.
第１図は本発明の一実施例を示す斜視図、第２図は第１
図に示す転写ガイドシートの一例を示す平面図である。FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG. 2 is a perspective view showing one embodiment of the present invention.
It is a top view which shows an example of the transfer guide sheet shown in a figure.
第１図に示す転写帯電器は、転写帯電板２と、ホルダ３
，４と、転写帯電ワイヤ５と、転写ガイドシートｌとで
構成される。The transfer charging device shown in FIG. 1 includes a transfer charging plate 2 and a holder 3.
, 4, a transfer charging wire 5, and a transfer guide sheet l.
ホルダ３，４は転写帯電ワイヤを保持するために転写帯
電板２の両端に設けられる。Holders 3 and 4 are provided at both ends of the transfer charging plate 2 to hold the transfer charging wire.
転写ガイドシー）１はポリイミド（ＰＩ）樹脂フィルム
からなり、ガイド部Ｃと、このガイド部Ｃの両端に設け
られている。このガイド部Ｃが転写帯電板２の上面の開
口部ｅに位置するように、複数枚の転写ガイドシート１
の貼付部ａ、ｂが転写帯電板２の両側面に貼付される。The transfer guide sheet 1 is made of a polyimide (PI) resin film, and is provided at a guide portion C and at both ends of this guide portion C. A plurality of transfer guide sheets 1 are arranged so that the guide portion C is located in the opening e on the upper surface of the transfer charging plate 2.
Pasting parts a and b are pasted on both sides of the transfer charging plate 2.
このように転写ガイドシート１のガイド部Ｃが開口部に
位置するように貼付されることにより、開口部ｅが保護
され用紙が転写帯電器の中に巻き込まないように防止さ
れる。By affixing the guide portion C of the transfer guide sheet 1 so as to be located in the opening in this manner, the opening e is protected and the paper is prevented from being caught in the transfer charger.
第３図は本発明の他の実施例を示す斜視図である。FIG. 3 is a perspective view showing another embodiment of the invention.
第３図に示す転写帯電器は転写ガイドとして第１図に示

からなる転写ガイドワイヤ６を用いたものであり、転写
帯電板２′の両側面に設けられたワイヤ停止部ｄで停止
されてジグザグに開口部ｅの上に張られる。The transfer charger shown in FIG. 3 uses a transfer guide wire 6 made of polyimide (PI) resin as a transfer guide instead of the transfer guide sheet 1 shown in FIG. The wire is stopped at a wire stop d provided in the wire and stretched over the opening e in a zigzag manner.
これにより、第１図に示す転写帯電器と同様に開口部ｅ
が保護され、用紙の巻込防止が遠戚される。As a result, the opening e is opened similarly to the transfer charger shown in FIG.
is protected, and the prevention of paper getting caught is a distant relative.
本発明の転写帯電器は、ポリイミドからなる転写ガイド
を設けることにより、浮遊トナーが付着しにくく、コロ
ナ放電による電位分布を乱すことの少なくできるため、
用紙の乱れや転写不良を減少できるという効果がある。By providing a transfer guide made of polyimide, the transfer charger of the present invention prevents floating toner from adhering to the charger and reduces disturbance of potential distribution due to corona discharge.
This has the effect of reducing paper disturbances and transfer defects.
