ABSTRACT:
An ink-landing-position control electrode is provided in such a way that one end of the control electrode is positioned adjacent to the back of a recording medium in opposed relationship with a predetermined position on the recording medium at which a charged ink drop must be deposited. The control electrode is charged oppositely of the charge on an ink drop in such a way that the electric lines of force of the electric field established by the control electrode are concentrated at the landing position, whereby a charged ink drop is forced to land at the predetermined position even when it is influenced by aerodynamic and electrostatic disturbances while it is in flight. The control electrode can also be used to eliminate an inclination of a line of dots deposited by a stream of charged ink drops issued from one nozzle when a recording medium is transported in the direction perpendicular to the traveling path of an ink-jet print head.
