Abstract

In a highlight color copier, one developer unit employs black toner and the other a colored toner. The black toner is magnetic while the colored toner is non-magnetic. During cleaning, the black liquid developer and the colored liquid developer are mixed. A magnetic separator may be used to filter out the black toner. The separator includes a tube filled with steel wool surrounded by a magnet. The magnet may be a permanent magnet or an electromagnet. The steel matrix provides the high magnetic gradients required for efficient capturing of the black magnetic toner to clean the colored liquid developer.
