Abstract
An image-forming element for an electrostatic printer is provided with an endless support having thereon a dielectric surface layer and a number of image-forming electrodes beneath the surface of the dielectric layer. In the zone of the image-forming element that is used for image formation, the electrodes extend parallel to one another in the form of helix, having a pitch which is at least equal to the working width of the image-forming element so that each electrode appears only once in a line of the image. Each electrode is connected to a voltage means for supplying voltage to the electrodes. The voltage means is disposed on the surface of the endless support outside the zone used for image formation.
