Claims

[Claims for Utility Model Registration] 1. A rotating roller with a polygonal cross section that rotates around a horizontal axis is provided at the inlet of the toner tank, and an elastic blade is pressed against the outer surface of the rotating roller from the toner tank side for cleaning. The residual toner scraped from the photoreceptor by a blade or the like is sent into the toner tank by the rotation of the rotating roller, and the residual toner is accumulated near the entrance of the toner tank by the movement of the elastic blade caused by the rotation of the rotating roller. In the cleaning device for an electrophotographic recording device, the rotating roller is continuously twisted in the axial direction, and the elastic blade is attached to the outer surface of the rotating roller. A cleaning device for electrophotographic recording devices that presses against the tip of the device. 2. The cleaning device for an electrophotographic recording device according to claim 1, wherein a plurality of notches are provided at appropriate intervals in the longitudinal direction of the tip of the elastic blade.
