Cleaning unit, image carrying unit and image forming apparatus using the same

Abstract

The invention relates to a cleaning unit, an image carrying unit using the cleaning unit and image forming apparatus. The object of the invention is to provides a cleaning unit capable of transporting the waste material removed by a cleaning member to a transport-effective area of the ejection member with reduced structure cost compared to the brush roller. The cleaning unit comprises: a cleaning scaper 61; and a toner recovery coil 65 at the position away from the surface of a sensitization body 3 for delivering the waste material removed by the cleaning scaper 61 from the surface of the sensitization body 3 and removed waste material outside of the cleaning unit 6, characterized in that the toner recovery coil 65 comprises a recovery unit 63 for delivering the waste material to a toner recovery transfer channel 68 with the toner recovery coil and the recovery unit 63 comprises a vane rotating part 63a capable of rotating along a rotation axle 63c parallel to the rotation axle direction of the sensitization body 3 and the waste material is delivered by the rotation of the vane rotating part 63a along the rotation axle 63c as center.

Description

technical field [0001] The present invention relates to a cleaning device used in image forming devices such as copiers, facsimile machines, and printers, and to an image carrier device and an image forming device including the cleaning device. Background technique [0002] In the prior art, the photoreceptor in the image forming device is usually cleaned by a cleaning device using a scraper cleaning method. The cleaning device uses a rubber-made scraper to contact the photoreceptor to be cleaned, and removes residues after the toner image is transferred. Residues such as toner on the photoreceptor. In the cleaning device of the blade cleaning method, a brush roller for assisting cleaning is provided upstream in the moving direction of the photoreceptor surface of the cleaning blade. [0003] In addition, the cleaning device also has a discharge member such as a toner recovery coil for sending waste powder such as toner removed from the surface of the photoreceptor to a con...

AI Technical Summary

Problems solved by technology

Also, in the structure in which the toner sent outside the unit is sent to the waste toner tank as waste toner, the above-mentioned problems also occur.

In addition, the structure of the photoreceptor as the cleaning object of the cleaning device has been described above. However, the cleaning object is not limited to the photoreceptor. The intermediate transfer body or the transfer transport body is also the cleaning object. The same problem occurs in the cleaning device of the surface moving body to which waste powder such as toner adheres

Furthermore, in addition to the scraper-shaped part, as long as it is in contact with the cleaning object and blocks the waste powder upstream in the moving direction of the surface of the cleaning object, or scrapes the waste powder upstream in the moving direction of the surface to clean the cleaning object, and from the cleaning object The above-mentioned problems will occur in parts that separate the cleaned waste powder from the surface of the object
