Claims

[Claims for Utility Model Registration] 1. A resist that removes paper dust, toner, etc. attached to a pair of registration rollers that convey a sheet of paper fed from a paper feeding device at a timing that matches the image on a photoreceptor. In the roller cleaning device, a cleaning brush whose brush portion slides in sliding contact with at least one of the registration rollers along an axial direction on an outer circumferential surface of the registration roller, and a brush interlocking rotation means for rotating the cleaning brush in conjunction with the registration roller. A registration roller cleaning device comprising: 2. The registration roller cleaning device according to claim 1, wherein a cam rod is formed on one of the rotating shaft of the cleaning brush and a bearing that supports the rotating shaft, and a cam that slides in contact with the cam rod is formed or integrally attached to the other, and A biasing force is applied to the rotating shaft by a spring in a direction that always brings the cam rod and the cam into sliding contact, so that when the rotating shaft rotates, the cleaning brush reciprocates in the axial direction. Registration roller cleaning device. 3. The registration roller cleaning device according to claim 1 or 2, wherein the cleaning brush is brought into sliding contact with the paper delivery side of the driving side registration roller of the pair of registration rollers, and is rotated in a direction opposite to the rotation of the registration roller. A registration roller cleaning device characterized in that:
