Abstract
An apparatus and method for stopping rotation and retracting a cleaning brush away from contact regions to avoid the occurrence of flat spots or voids in the cleaning brush and prevent toner emissions from the cleaning brush as it is retracted. The cleaning brush is rotated about a pivot point to move the cleaning brush away from contact with the photoreceptor and the detoning roll. The pivot point is positioned so that the variation in interference to the detoning roll is minimized for variations in the interference and location of the brush against the photoreceptor. Each cleaning brush has a housing that moves in conjunction with the movement of the cleaning brush in order to avoid contact between the housing and the cleaning brush. This cleaning apparatus also enables development of multi-layer color images.
