Abstract
A device for the transport and/or metering of marking material includes a plurality of phased electrodes, for example formed on a substrate. An electrostatic traveling wave may be generated along the electrodes to sequentially attract particles of marking material, and thereby transport them to a desired location. The electrodes may be formed in a planar structure. A matrix interconnection scheme allows for reduced lead count.
