An image-forming device comprising a movable image-recording element (1) comprising a support (2) with a dielectric surface layer (7) and, beneath the same, a set of separately energisable image-forming electrodes (5) insulated from one another, an image-forming zone situated along the trajectory of the image-recording element, in which zone a co-acting electrode (6) is disposed a short distance above the dielectric surface (7) of the image-recording element (1), and control means (3) in order to apply a voltage between the image-forming electrodes (5) and the co-acting electrode (6) in accordance with an image pattern for recording, in order to deposit toner powder present in the image-forming zone on the surface of the image-recording element in accordance with the image pattern. In order to prevent burn-out of the image-forming electrodes and undue limitation of the image-forming device processing speed, the image-forming electrodes (5) consist of an electrically conductive material having a resistivity of between 0.008 and 0.2 OMEGA .cm. |
