| 摘要 |
A printhead structure (106) for use in a DEP (Direct Electrostatic Printing) is provided, made from an insulating material comprising a control electrode in combination with printing apertures (107) and being installed between a toner delivery means (101) and a image receiving substrate (109), characterised in that the printhead structure comprises: (i) one individual control electrode (106a) around each aperture (107) on one side of the insulating material (106d) of the printhead structure, (ii) one individual shield electrode (106b) around each aperture (107) on the other side of the insulating material (106d) of the printhead structure, wherein each single electrode of the individual control electrodes (106a) and each single electrode of the individual shield electrodes (106b) arranged around each aperture (107) are connected to each other via metallisation (106c) through the single aperture (107), forming a single printing electrode around each aperture (107). <IMAGE>
