Abstract

A transfer roller assembly including a transfer roller and a rotary cleaning brush for an electrostatographic machine. The transfer roller assembly is rotated about a support shaft and in pressure contact with the photoconductive surface during the image transfer mode therefor. The transfer roller assembly includes a rotating cleaning brush in cleaning contact with the transfer roller and is movable with the roller about the support shaft. Separate drive mechanisms from a single drive member on the assembly provide independent rotation to the roller and the brush. [US3847119A]

Claims (1)

1. An electrostatographlc apparatus having a movable photoconductive surface and means for moving transfer sheet material into contact with the photoconductive surface to effect transfer of toner from photoconductive surfaee to the transfer material a transfer member adapted for movement into contact with the photoconductive with surface transfer material means moving the contactin surface of said member at a speed with the movable photoconductive an cleaning member mounted for interferin engagement with the surface of said transfer and means for pivotally supporting said transfer member and said cleaning member so that said transfer member can be moved into out of contac with the photoconductive surface as said pivotally supporting means permitting said transfer member and said cleaning member to be moved as a apparatus of claim 1 wherein said transfer member is a apparatus of claim 1 claim 2 wherein said cleaning member is a rctery cleaning brush mounted for rotation and having bristles in interfering engagement with the surface of said transfer apparatus of claim and including means for tatin said brush with a faster surface velocity than said transfer The apparatus of claim 4 wherein speed of rotation the brush is approximately at a ratio of relative to the speed of said transfer The apparatus of claim 2 or any one claims 3 to 5 as dependent on claim 2 wherein said transfer roller and said are arranged to rotate in the same The apparatus any one of claims 1 to 6 including means for establishing an electrical potential between said and the photoconductive surface the transfer of toner images to the transfer An apparatus substantially hereinbefore described with reference and as tically the accompanying Fo the Applicants AMD insufficientOCRQuality
