An image-forming element for an electrostatic printer, consisting of an endless support (1) with thereon a diëlectric surface layer and a number of image-forming electrodes (2) beneath the surface of said layer. In the zone of the image-forming element that is used for the image formation, the electrodes (2) extend parallel to one another, each according to a helix having a pitch which is at least equal to the working width of the image-forming element. Each electrode (2) is connected to means (5) for supplying voltage to the electrodes (2), the means (5) being disposed on the support (1) outside the zone used for the image formation. An electrostatic printer in which the image-forming element is used, is also described. |
