Abstract:
1. Image-forming element for a printing apparatus which comprises a support structure with a plurality of electrodes of a first type disposed thereon and an electronic control unit for energizing electrodes, wherein the image-forming element further includes a plurality of electrodes of a second type, each one of said electrodes of the second type being arranged for interacting capacitively through a dielectric layer with a number of electrodes of the first type, forming a group, the electronic control unit containing a first series of drivers for energizing the electrodes of the first type, each of said drivers being suited for energizing one electrode of the first type within each group and a second series of drivers for individually energizing the electrodes of the second type, the first and second series of drivers being arranged such that the electrodes of the first type can be individually activated, image wise.
