Abstract
A device for the transport of particulate marking material includes a plurality of interdigitated electrodes formed on a substrate. An electrostatic traveling wave may be generated across the electrodes to sequentially attract particles of marking material, and thereby transport them to a desired location. The electrodes may be integrally formed with driving circuitry, and may be staggered to minimize or eliminate cross-talk.
