Focussed ion stream technology is directed to apparatus and methods for focusing, deflecting and switching ions in an airless ionographic writing system. Typically, the focusing, deflecting and switching operations are accomplished across a thin insulator having apertures and electrodes disposed on both sides thereof. This disclosure proposes a novel method to employ focussed ion stream technology as illustrated in the figure. As shown, the focussed ion stream FIST head 10 is in propinquity with one side 12 of the insulating receiver surface 14. A biased developer roller 18 contacts the opposite surface. Charges written on the focussed ion stream side attract and attach toner particles 20 to the opposite face.
