Abstract
A recording unit is disclosed which is provided with a hollow, very small nozzle supplied with a liquid imaging material, an electrode plate having formed therein a through hole coaxial with the nozzle and disposed opposite to the tip of the nozzle and a ring of small diameter disposed on the nozzle coaxially therewith in the vicinity of its tip or between the nozzle and the electrode plate. A convergent or unfluctuated jet of the liquid imaging material produced by a voltage applied between the nozzle and the electrode plate disposed opposite thereto is directed through the through hole of the electrode plate to a recording member or medium placed adjacent to the electrode plate on the opposite side from the nozzle. The convergent jet of the liquid imaging material thus produced is made intermittent by applying a voltage to the ring, thereby to record images.
