Abstract (en)

[origin: EP0911706A1] A device for direct electrostatic printing is provided comprising means for creating a flow of charged toner particles (102) from a means (103) for delivering charged toner particles, having a surface bearing toner particles, to an image receiving substrate (108) applying a DC-potential difference between the means for delivering charged toner particles and the image receiving substrate and a printhead structure (106) having control electrodes (106a), interposed in the flow of toner particles for image-wise controlling the flow of toner particles, the printhead structure controlling the flow of toner particles by switching an AC-field (119) between the toner delivery means and the control electrodes on for pixels of image density and off for pixels of no image density. <IMAGE>
