が大となる欠点も生じる。 Conventionally, in an electrophotographic copying machine or the like, an electrostatic latent image formed on the surface of a photoreceptor is developed to form a toner image, and after the toner image is transferred to transfer paper, the toner remaining on the surface of the photoreceptor is cleaned. A fur brush cleaning device using a fur brush is used. Such fur brushes are usually
It is rotatably supported by a housing or the like and rotated in the same direction as the photoreceptor drum, and at the contact surface between the two, brush bristles strongly rub the circumferential surface of the photoreceptor drum in the opposite direction to sweep away residual toner. If a transfer failure occurs due to the properties of the transfer paper, such as an increase in moisture content, or if the transfer paper jams, a large amount of untransferred toner will remain on the photoconductor, but in this case, be prepared. The fur brush is
Usually, it is rotated at a high speed of 800 to 1,500 rpm, which is ample. However, toner and the like adhere to the surface of the photoreceptor to form a film due to the pressing force of the fur brush rotating at high speed. This is a phenomenon called toner filming, and this phenomenon deteriorates the electrostatic properties of the photoreceptor.
This causes deterioration in the quality of copied images such as background stains, density unevenness, and image bleeding. Therefore, regular maintenance is frequently required, and the photoconductor on which this toner film has formed cannot be removed without using a special abrasive, which causes uneven cleaning and is technically difficult. There were some shortcomings in terms of maintenance and management. In addition, when the fur brush is rotated at high speed, the fur brush itself generates wind, resulting in a large amount of toner being scattered.

It is characterized by weakening the toner filming phenomenon and suppressing the occurrence of the toner filming phenomenon. That is, the first invention sets the relative speeds of the fur brush surface and the photoreceptor surface when they pass each other within a certain allowable range, and the second invention sets the fur brush surface moving speed within a certain tolerance range. The speed is set to be lower than the photoreceptor surface movement speed.

If a dedicated path is provided from the outside of the installed machine and the photoreceptor surface and the fur brush itself are cooled,
The generation of toner film can be more effectively suppressed.

定着され複写画紙が出来上がる。 Next, the operation of the electrophotographic copying machine configured as above will be explained. As the photoreceptor drum 1 rotates, the surface of the photoreceptor is charged by the charger 2.
The original image is uniformly charged, and the image exposure device 3 exposes the original image to selectively erase the charged charges, forming an electrostatic latent image. This electrostatic latent image is developed by the developing device 4 to form a toner image. Then, the toner image is transferred to the transfer paper fed from the paper feed roller 10 by the transfer device 5, the toner remaining on the surface of the photoconductor is neutralized by the static eliminator 7, and the photoconductor is removed by the fur brush cleaning device 8. The toner is swept away from the body surface, and finally the photoreceptor itself is again neutralized by the static eliminator 9 to prepare for the next copying process. On the other hand, the transfer paper on which the toner image has been transferred is separated from the photoreceptor drum 1 by a separator 11, and is separated from the photoreceptor drum 1 by a conveyance roller 12.
The image is then sent to the fixing section and heated and fixed by the fixing heater 13 to complete copy paper.

とによつて、上記の懸念は解消される。 Here, as shown in FIG. 2, the operation based on the present invention is performed by assuming that the surface moving speed, that is, the circumferential speed, of the photoreceptor drum 1 is V1, and that the surface of the fur brush is the surface in contact with the photoreceptor (double-dashed line). The surface moving speed, that is, the circumferential speed will be explained as V2 . The circumferential speed V 1 is determined by the copying speed set for the copying machine. Normally, V 1 is 100 mm/sec in a low-speed machine with transfer paper size A4 and 10 cpm, and V 1 is 600 mm/sec in a high-speed machine with A4 size 60 cpm. 1st
According to experiments conducted by the inventor regarding the invention, as shown in FIG .
When the speed exceeds mm/sec, the amount of toner film generated increases rapidly, resulting in a deterioration in the quality of copied images that is practically unacceptable. Therefore, empirically, the relative velocity (V 1 +V 2 ) is determined as 100mm/sec<V 1 +V 2 <1600
It was found that it is sufficient to control the temperature within the permissible range of mm/sec. Now, the photoreceptor peripheral speed V 1 is 100 in a low-speed machine.
If mm/sec, the fur brush peripheral speed V 2 is 0
Since it is permissible within the range of mm/sec < V 2 < 1500 mm/sec, the rotational speed of the fur brush may be variably controlled within the above range by the control unit 13 as necessary, such as in the case of the aforementioned transfer failure. . or,
The circumferential speed V 1 of the photoreceptor is 600 mm/
sec, the fur brush circumferential speed V 2 is calculated as -
500mm/sec<V 2 <1,000mm/sec, but since it is unreasonable for the fur brush to rotate in the opposite direction, the appropriate range is 0mm/sec<V 2 <1,000mm/sec. . Here, for high-speed aircraft, V 2
The maximum speed is 1,000mm/sec, and the brush diameter is 90mm.
In this case, the fur brush rotation speed is as low as 216 rpm, which is about 1/5 of the conventional speed of around 1,000 rpm. Therefore, there is a concern that the cleaning performance will deteriorate, but the brush bristles 8a
The above concerns can be resolved by using electrostatically semiconductor fibers, specifically acrylic fibers mixed with carbon.

る。 Next, according to the inventor's experiment regarding the second invention, as shown in FIG .
When V 1 /V 2 became larger than 1.0, there was a tendency for the amount of toner film generated, which had been almost constant until then, to decrease rapidly. The cause of this phenomenon is
It is presumed that this is because when the fur brush sweeps off the residual toner adhering to the photoreceptor, if the circumferential speed of the photoreceptor is higher than that of the photoreceptor, the force exerted by the fur brush becomes such that the toner is rubbed against the photoreceptor. Therefore, from the above experimental results, it has been found empirically that it is sufficient to control both circumferential speeds to maintain the relationship of V 1 ≧V 2 >0. Here, V 1 is 600mm/600mm for a high-speed aircraft as mentioned above.
sec, and 100 mm/sec for low-speed machines, which are determined by the characteristics of each copying machine.In the end, the fur brush circumferential speed V2 is controlled within the range below the photoconductor circumferential speed as necessary, such as in the case of transfer failure. Just do it. For example, in the case of a low-speed aircraft, 0 mm/sec<V 2 ≦100 mm/sec.

の冷却効果が増すことになる。 Air for conveying the swept toner is forcibly introduced into the air chamber 15 of FIG. 1 from outside the copying machine using a fan (not shown) or the like. On the other hand, since the fur brush cleaning device uses forced suction to convey the swept toner, the air in the air chamber 15 passes from the discharge port 16 near the static eliminator 7,
It quickly flows to the fur brush cleaning device 8 and cools the surface of the photoreceptor and the fur brush.
At this time, from the air chamber 15 to the conveyance roller 12
Fan 1 so that some of the outside air flows toward
8, an air curtain is formed between the fixing heater 13 and the fur brush cleaning device 8, and the heat generated in the fixing heater 13 is blocked and does not propagate to the fur brush cleaning device 8. This increases the cooling effect of the fur brush and the surface of the photoreceptor.
