本発明は画像記録装置、特に乾式現像用トナーを用いる
電子写真複写機に適用しうる転写後の残留トナーの回収
装置に関する。DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an apparatus for recovering residual toner after transfer, which can be applied to image recording apparatuses, particularly electrophotographic copying machines using dry developing toner.

。2. Description of the Related Art A configuration is known in which residual toner is collected after a toner image on a photoreceptor, which is a latent image carrier, of a copying machine is transferred to a transfer material such as a sheet. FIG. 1 shows a known toner recovery device, in which a cleaning brush 1 for removing residual toner on a photoreceptor (not shown) rotates in the direction of arrow A, scrapes off the toner, and transfers the toner into a toner conveying path 2. Store it.

とがある。A toner collection wire 3 that is rotatable and given a driving force is provided in the toner transport path, and is adapted to move the toner stored in the transport path and drop it into the toner collection container 4. In this case, the rotation of the cleaning brush 1 generates turbulent air in the direction of arrow B, and this turbulent air flows into the toner collection container 4 using the toner transport path 2 as a ventilation path, and the connecting portion between the collection container and the toner transport path. Gap 5, 5
Air is exhausted from '. Accordingly, the recovered toner transferred through the toner conveying path 2 by the turbulent air becomes a powder mist, and is discharged from the toner recovery container through the gaps 5 and 5'. Leakage of collected toner outside the collection container not only pollutes the inside of the copying machine, but also especially when the detector 6 for measuring the amount of collected toner uses an optical detection method or a magnetic detection method as shown in FIG. may flow into the detector and cause it to malfunction.

容器に送り込まれるようなことは生じない。Configuration The configuration of the present invention will be explained below based on one embodiment. In FIG. 2, a toner discharge roller 8 having a helical groove is attached to the other end of a shaft 7 of a toner collection wire 3 rotatably provided within the toner transport path 2. As shown in FIG. As the cleaning brush 1 rotates, residual toner on the photoreceptor is captured by the cleaning brush and stored in the toner transport path 2. The shaft 7 of the toner collection wire 3 is given a rotational force by a drive source (not shown), and the toner remaining below the toner collection path 2 is transferred to the left, and further sent into the helical groove of the toner discharge roller 8. The toner is then discharged into the toner collection container 4 shown in FIG. With the above configuration, the gap between the convex portion of the toner discharge roller 8 and the pipe wall of the discharge portion 2' of the toner conveyance path 2 is small, so the flow of air generated by the rotation of the cleaning brush 1 is blocked.
There is no possibility that the toner becomes powdery in the toner transport path and is sent to the toner collection container.

れた。According to experiments conducted by the present inventors, in the conventional example shown in Figure 1, the number of floating toner particles measured using a dust monitor was 32,000 particles/m3 inside the toner collection container, and 8,700 particles/m3 inside the machine outside the collection container. /m3 was measured. On the other hand, in two experimental examples according to the present invention, the following measurement results were obtained.

脂が適している。It can be seen that by providing a toner discharge roller having a helical groove in this manner, it is possible to reduce the number of toner floating far more effectively than in the conventional method. The toner discharge roller is preferably made of metal such as aluminum or resin such as polycarbonate.
