Abstract (en)

A DEP device comprising : a non-magnetic mono-component development system comprising a toner dispensing part (108) and a conveyer for charged toner particles (103), placed in the DEP device so that both touch each other for transferring charged toner particles from the toner dispensing part to the conveyor, one or more voltage sources (V1, V4) for creating an electric field between the conveyor and an image receiving member (109), for forming a flow (111) of charged toner particles to the image receiving member, and a printhead structure (106), placed in the flow and having printing apertures (107) coupled to control electrodes (106a) coupled to a control voltage (V3), being image wise modulated for image-wise depositing toner particles on the image receiving member. <IMAGE>
