ABSTRACT:
Electrostatographic toning with charged toner particles which are transported along a conveyor having an array of repeating sets of electrodes upon which an electrostatic traveling wave pattern is established. The traveling wave pattern causes already charged toner particles to slide and roll along the conveyor to a selection site whereat individual toner particles are either directed toward the receiver or are returned to a developer reservoir. The width of each of the electrodes for the traveling wave grid is comparable to the size of the toner particles such that the particles are transported individually along the conveyor. At the selection site, unwanted particles are deflected from the path to a receiver. The receiver can be placed against a conveyor plate to avoid the divergence and bouncing problems.
