Abstract: An image-forming device with a repeatedly usable image-recording element bearing a dielectric surface layer, beneath which is a system of separately energizable image-forming electrodes interconnected by a material whose resistance is between that of the dielectric surface layer and that of the image-forming electrode and is preferably a factor of 10.sup.2 -10.sup.4 lower than that of the dielectric surface layer, the dielectric surface layer and the material having the lower resistance preferably being formed as one continuous layer which bottom part has a lower resistance than in the top part.

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.
