ABSTRACT:
A Direct Electrostatic Printing (DEP) device is provided that includes a back electrode (105), a printhead structure having an insulating substrate (102), a control electrode (102a) and a slit aperture (103) through which a particle flow can be electrically modulated by the control electrode (102a), and a toner delivery means (101), in which control electrodes (102a) are present only on one side of the slit aperture. In a preferred embodiment the printhead structure is realized by a slit having two sides, side A (SA) and side B (SB), defined by two edges (A and B), which are formed by at least one sheet of insulating material. The insulating material has an elasticity modulus (Young's Modulus, YM) fulfilling the equation 0.1 GPa.ltoreq.YM.ltoreq.10 GPa and the edges A and B are placed with respect to each other at an angle .alpha. fulfilling the equation 0.degree..ltoreq..alpha.<45.degree..
