Abstract (en)
[origin: EP0816944A1] A device for direct electrostatic printing (DEP) is provided comprising a printhead structure, having two major faces, and a toner delivery means having an external surface wherein the printhead structure is kept at a constant distance, D, from the external surface of a toner delivery means, moving in a direction A, by spacing means forming an angle between 45 DEG and 0 DEG with direction A and being located at a distance d from each other such that 1 cm ≤ d ≤ 50 cm. In a preferred embodiment the spacing means are located at a distance d such that 5 cm ≤ d ≤ 35 cm and the constant distance D is kept between 25 and 500 mu m. <IMAGE>
