A cleaning apparatus and method for removing residual toner from a photoconductor in a color copier. The apparatus includes a magnetic brush for removing color toner particles from the photoconductor as the different color toner particles serially appear at the cleaning station. A detoning roller located proximate the magnetic brush has a portion thereof near the magnetic brush electrically biased to strip charged toner particles from the brush. A plurality of skiving blades serially operate on the detoning roller in accordance with the respective color of the toner particles to remove the particles from the roller. The portion of the detoning roller adjacent the skiving blades is electrically biased to repel the particles to facilitate their removal. Each of the skiving blades is associated with a respective collecting means for collecting color toner particles of a respective color. When toner particles of one color are being removed from the roller, the skiving blades associated with the other colors are moved to a position where they assist in closing off their respective collecting means from receiving airborne toner particles of colors not intended to be collected. The toner particles collected by the cleaning apparatus are therefore sufficiently free of cross-contamination to permit recirculation to their respective developer stations. |
