る。After the toner image is transferred, the untransferred toner 7 remaining on the surface of the photoreceptor 1 is scraped off by the blade 3, and then the sealing member 10 provided at the opening 48 of the housing 4 (i.e., the opening 48) is scraped off by the blade 3. A sealing member 10 is located at a portion 4a and is provided so as to be in contact with the surface of the photoreceptor 1.
) is collected into the opening 4a. The sealing member 10 is installed in an inclined manner to prevent the collected toner 7 from leaking from the lower opening of the housing 4 and to allow the scraped toner 7 to slide down into the conveyance path 6 of the housing 4. There is. Furthermore, the seal member 10 is fixed to the housing 4 so as to be in constant contact with the surface of the photoreceptor 1.
トナー搬送路６内には、スクリュー状に成形された回収
トナー搬送部材５が設けられていて、トナー搬送部材５
は、図示を省略した駆動源により一方向に回転される。A recovered toner conveying member 5 shaped like a screw is provided in the toner conveying path 6.
is rotated in one direction by a drive source (not shown).
すなわち、回収トナー７は、トナー搬送路６と搬送部材
５とのポンプ作用により一方向に搬送、排出される。That is, the collected toner 7 is transported and discharged in one direction by the pump action of the toner transport path 6 and the transport member 5.
以上の構成において、回収トナー搬送部材５は。 In the above configuration, the collected toner conveying member 5 is as follows.
角形の金属棒をスクリュー状に成形して形成されている
ので安価ではあるが、スクリュー外径精度や真直性には
、精度上バラツキがある。Since it is formed by molding a rectangular metal rod into a screw shape, it is inexpensive, but there are variations in accuracy in the screw outer diameter accuracy and straightness.
一方、トナー搬送路６を構成するハウジング４は、アル
ミサツシで成形されており、その形状精度には、ハウジ
ング成形時の歪や条件等によりバラツキを生じる。On the other hand, the housing 4 constituting the toner conveying path 6 is formed of aluminum sash, and its shape accuracy varies due to distortions and conditions during the housing molding.

It increases in height and exhibits a blocking phenomenon in which it accumulates and grows, becomes constantly attached to the photoreceptor 1, is carried as the photoreceptor 1 rotates, and reaches the blade 3, reducing the cleaning function of the blade 3. In addition, the weight of the toner 7 may cause the tip of the sealing member 10 to separate from the surface of the photoreceptor 1, reducing its sealing effect and contaminating the inside of the machine. Particularly when the cleaning device 2 is attached or removed, the accumulated toner 7 may be scattered inside the machine. This caused problems such as:

When the conveying gap 8 between the recovered toner conveying member 5 and the conveying path 6 is set to be large enough as shown in FIG.
Toner transport efficiency decreases. In addition, the toner 7 that is not transported accumulates on the sealing member 10, and as the number of printed sheets increases, the height increases and the toner 7 grows, exhibiting a blocking phenomenon, and constantly adheres to the photoreceptor 1. As the photoreceptor 1 rotates, the toner is transported and reaches the blade 3, reducing the cleaning function of the blade 3.
The cleaning device i2 is separated from the surface of the cleaning device i2, reducing its sealing effect and contaminating the inside of the machine. Particularly, when the cleaning device i2 is attached and detached, the accumulated toner 7 is scattered inside the machine.
