DIRECT PRINTING METHOD WITH IMPROVED CONTROL FUNCTION

摘要

An image-recording device (100) for recording an image on an image-receiving medium (200). The image-recording device comprises a toner particle source (110) for providing electrically charged toner particles, a voltage source (120), a printhead structure (130), and a back electrode (140). The printhead structure comprises control electrodes (133) for selectively opening or closing a plurarlity of apertures (134) arranged through the printhead structure. The control electrodes thus permit or restrict the transport of toner particles to control the amount of toner particles transported through the plurality of apertures in order to thereby enable the formation of a toner particle image on the image receiving medium. The plurality of apertures have an oblong shape with a major axis (135) and a minor axis (136). The major axis is substantially parallel to a feeding direction (A) of the image-receiving medium.
