ABSTRACT:
Apparatus for applying toner to a tape which has toner-attracting images thereon, including a chamber containing toner, a chamber inlet located below the top of the toner, a chamber outlet above the top of the toner, and a tape guide which is convex along the tape path which leads through the toner to minimize toner pickup on the rear face of the tape. A vacuum is maintained at the top of the chamber to create an inflow of air at the tape outlet, to sweep back loose toner.
