Claim One:
1. An electronic printing apparatus for forming images on a receiver, comprising: a) means for storing a digital image; b) the receiver including field-driven particles in a matrix that change optical density in response to an applied electric field, a substrate, and a conductive portion disposed between the matrix and the substrate; c) an array of electrodes cooperating with the conductive portion and a common electrode capacitively coupled to the conductive portion for selectively applying electric fields across the matrix at the image forming position so that the field-driven particles change optical density; and d) electronic control means electrically coupled to the array and the conductive portion for selectively applying voltages to the array so that fields are applied between the array of electrodes and the conductive portion at the image forming position to field-driven particles at particular locations on the receiver corresponding to pixels in the stored image whereby an image is produced in the receiver corresponding to the stored image.
