Abstract

PURPOSE:To fade white or black stripes developed on joints of printed recording images by displacing ink jet particles injected through separate nozzles slightly at random in the direction of deflected scanning so as to form a multinozzle. CONSTITUTION:A plurality of ink jet recorders are arranged straight in the direction of arrow A while a recording paper 8 moves in rectangular direction to the surface of a paper to form a multinozzle ink jet recorder. An output signal voltage from a random signal voltage generator circuit 15 is sampled with a signal (d) from a modulation circuit 14 in a multiplex circuit 16 to become a signal (e), and after multiplexed, it applied to a charge electrode 5 as a signal (f). This allows each ink jet particle to displace from a regular printing position in the direction of deflected scanning by the level of a random signal voltage multiplexed in the multiplex circuit 16 thereby the joints are roftened to a large extent.
