本発明は、電子写真複写機を含む静電記録装置における
像形成体上の表面に付着した残留トナー等を除去するク
リーニング装置の改良に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an improvement in a cleaning device for removing residual toner etc. adhering to the surface of an image forming body in an electrostatic recording device including an electrophotographic copying machine. It is.
電子写真複写機において、記録紙に転写を終えた像形成
体は、新たな画像形成のための処理を受ける前に、その
表面に付着したいわゆる残留トナーを除去されねばなら
ない。In an electrophotographic copying machine, the so-called residual toner adhering to the surface of the image forming body must be removed before it undergoes processing for forming a new image after being transferred to the recording paper.
そのため、像形成体ドラムの局面に接してクリーニング
部材を配設し、像形成体ドラムの自転に共働して自動的
に残留トナーを離脱することのできる各種のクリーニン
グ装置が提案されている。Therefore, various cleaning devices have been proposed in which a cleaning member is disposed in contact with the surface of the image forming drum and can automatically remove residual toner in cooperation with the rotation of the image forming drum.

ナーを飛散、浮遊させない特色を有しているので多（の
電子写真装置に採用されている。Among them, the blade cleaning device has the simplest structure, yet has high cleaning efficiency, and has the feature of not causing separated toner to scatter or float, so it is used in many electrophotographic devices.

でなく、トナーの回収にも不都合を来すという欠点を持
っている。However, on the other hand, the toner separated by the grade will naturally fall onto the surface of the image forming drum and will accumulate and adhere to the residual toner on the image forming drum, which will only increase the cleaning burden on the blade. Moreover, it also has the disadvantage of causing inconvenience in toner collection.
また落下したトナーがクリーニング装置外に洩出し外部
を汚染してしまう欠点もある。Another disadvantage is that the fallen toner leaks out of the cleaning device and contaminates the outside.

公報に記載されている。As a means for solving this drawback in the blade cleaning device, a means as shown in FIGS. 3a and 3b is known. That is, a Mylar blade is detached from the cleaning blade 2 below the cleaning grade 2 (referred to as upstream when viewed from the rotational direction of the image forming body drum 10) and is used to remove toner falling on the surface of the image forming body drum 10. 4a is provided so as to be in sliding contact with the surface of the image forming body drum (Fig. 3a),
Upstream of the cleaning blade 2, a foamed roll 4b made of foamed plastic or the like is installed upstream of the cleaning grade 2 and is rotated counterclockwise so as to be in sliding contact with the surface of the image forming drum (Fig. 3b). ), but in either case, the separated toner is pressed against the surface of the image forming drum again, causing the toner to form a film, causing toner leakage, which may cause a malfunction of the device, or the image forming drum 1 There were drawbacks such as damage and deterioration. Japanese Patent Publication No. 47-42340 describes an apparatus for removing toner separated by cleaning grade, which eliminates the above-mentioned drawbacks.

するため直流高圧電源７ｂが接続されている。As shown in FIG. 1, a cleaning blade 2 and a toner collection roller 3 made of a conductive material are placed upstream of the cleaning blade 2 and slightly spaced from the surface of the image forming drum 1. The circumferential speed of the toner collecting roller 30 and the direction of movement in the gap are made to be the same as the circumferential speed of the image forming drum. A DC high-voltage power source 7b is connected to the toner collection roller 3 in order to apply a potential having a polarity opposite to that of the toner and sufficient to attract the toner to the surface of the toner collection roller 3.

きず、条件によっては有害であることすらあった。However, the above-mentioned Japanese Patent Publication No. 47-42340 discloses the mutual positional relationship between the cleaning blade 2 and the toner recovery roller 3, the gap amount between the surface of the image forming body drum 1 and the toner recovery roller 3, and the toner recovery roller 3. There was no detailed description of the interrelationship with the voltage applied to the voltage, which lacked precision, made it impossible to demonstrate its performance in practice, and could even be harmful depending on the conditions.

Based on this value, a grade cleaning device having a toner collection roller to which the above-mentioned high voltage was applied is configured, and the image forming body is It is an object of the present invention to provide an apparatus that can almost completely remove residual toner on an image forming member without causing damage.

本発明者らは回収ローラーに関し、次の実験結果を得た

れない。」
第２に像形成体ドラム１の表面とトナー回収ローラー３
とのギャップ量とトナー回収ｐ−ラー３に印加する電位
の関係について種々実験を行った。First, as a result of various experiments regarding the installation position and rotation speed of the toner collection roller 3, we found that it is better to install the toner collection roller 3 as close to the cleaning blade 2 as possible for better toner collection efficiency.
Further, the relative drum speed between the toner collection roller 3 and the image forming body drum 1 is higher (and the preferable range of the circumferential speed V is O≦v
<100mm/IM, but is not limited to this range. ” Second, the surface of the image forming body drum 1 and the toner collection roller 3
Various experiments were conducted regarding the relationship between the gap amount between the toner collector p-ler 3 and the potential applied to the toner collection p-ler 3.
その結果、
１）トナー電荷の極性とトナー回収ローラーへの印加電
圧の極性は反対であることが必要である。As a result: 1) The polarity of the toner charge and the polarity of the voltage applied to the toner collection roller must be opposite.
１１）ギヤツブｄは小さい方がトナー回収効率は良いが
、ギャップｄを大きくするに従い印加電圧を大きくする
ことによっても同じ回収効率を得ることができる。11) The smaller the gear d, the better the toner collection efficiency, but the same collection efficiency can be obtained by increasing the applied voltage as the gap d becomes larger.
１１１）印加電圧の大きさはギャップｄの値を一定にし
た場合ある値より小さくなると、急激に回収効率が悪く
なってトナーがギャップの間からこぼれ落ちるようにな
り、一方ある値より大きくすると、絶縁破壊を生じいわ
ゆる落雷現象を起してリークを発生し、しかも像形成体
を劣化させ、損傷を与えるようになる。111) If the magnitude of the applied voltage is smaller than a certain value when the value of the gap d is constant, the collection efficiency will suddenly deteriorate and toner will fall out from between the gaps, whereas if it is larger than a certain value, This causes dielectric breakdown and causes a so-called lightning strike phenomenon, causing leakage, and furthermore, deteriorating and damaging the image forming body.
１ｖ）上記の印加電圧の大きさとギャップｄの大きさと
の間には第２図に示すような関係が得られ使用可能範囲
の上限と下限については第２図より次のような関数関係
が得られた。1v) The relationship shown in Figure 2 is obtained between the magnitude of the above applied voltage and the size of the gap d, and the following functional relationship is obtained from Figure 2 regarding the upper and lower limits of the usable range. It was done.
上限 Ｖ ｍａｘ ＝ ４０００ ・ｄ ＋ ２００
ボルト下限 Ｖ ｍｉｎ ＝２０００−ｄ −２００
ボルト但し、ギヤノブｄの寸法単位はｎｏ
なお実用上はＶｍａｘ ” ４０００・ｄ ＋ １００

が好まし−・。Upper limit V max = 4000 ・d + 200
Volt lower limit V min =2000-d-200
Bolt However, the dimensional unit of gear knob d is no. In practical terms, Vmax is 4000・d + 100.
Vmin=2000·d-100 volts is preferable.
■）この結果はＯＰＣ感光体だけではな（Ｓｅ感光体に
ついても同じであった。(2) This result was not only true for the OPC photoreceptor (the same was true for the Se photoreceptor as well).

ラフから７００ｖに設定した。According to the above experimental results, the configuration and arrangement of each member are the same as in FIG. 1 described above, but the toner collection roller 3 is installed as close as possible to the cleaning blade 2,
The rotation speed is such that the relative circumferential speed V with respect to the image forming body drum 1 is O≦
Select it so that it is in the range of y < 100u+/sec (
The direction of rotation is opposite to that of the image forming drum 1 and is in the forward direction (see Figure 1). Also, the gear d between the toner collection roller 3 and the image forming drum 1 is used during assembly work or maintenance inspection of the device. It is a size that does not require harshness, and
02 to 0. Do not increase the voltage applied to the toner recovery p-ler 3 unnecessarily. :3rm, and the applied voltage was set to 700v from the graph of FIG.

ビス負担も大幅に軽減されることとなった。As a result of good cleaning of the electrostatic recording device equipped with the above-mentioned cleaning device, toner filming does not occur on the photoconductor, and dielectric breakdown of the photoconductor due to lightning strikes does not occur. It was confirmed that the lifespan of the photoreceptor was longer than before.In addition, the inside of the electrostatic recording device was much less contaminated by toner than before, so the accident rate was reduced, and the inside of the device was The burden of cleaning and other services has also been significantly reduced.
