摘要： A direct electrostatic printing device includes a printhead structure with apertures and control electrodes associated with the apertures for delivering toner from a toner source to a substrate in accordance with image data. A first voltage source is provided to establish a flow of toner particles from the toner source to the substrate. A second voltage source is provided to establish a control voltage between the toner source and the control electrodes to control toner flow in accordance with the image data. The second voltage source provides a first AC field between a toner source and the control electrodes to permit toner flow and a second, diminished, AC field between the toner source and the control electrodes in order to stop the toner flow.

The printing apertures are constructed and arranged such that, when applying a potential difference of 200V between the shield electrode and each individual control electrode, a current of no more that 50 .mu.A flows from each individual control electrode to the corresponding shield electrode through the corresponding printing aperture. Methods for forming the printing apertures in such a printhead are also disclosed.
