Abstract
An image-forming device comprising a movable image-recording element including a support with a dielectric surface layer and, beneath which, a set of separately energizable image-forming electrodes insulated from one another is provided, an image-forming zone situated along the trajectory of the image-recording element, in which zone a co-acting electrode is disposed a short distance above the dielectric surface of the image-recording element, and control means in order to apply a voltage between the image-forming electrodes and the co-acting electrode in accordance with an image pattern for recording, by depositing toner powder present in the image-forming zone on the surface of the image-recording element in accordance with the image pattern. The image-forming electrodes have an electrical resistivity of between 0.008 and 0.2 .OMEGA..cm.
