Abstract

PURPOSE:To obtain an ink jet recording apparatus which is designed capable of printing on a line to an entire printing level surface of a recording paper at a time by providing it with a charging electrode, which is to selectively charge ink drops from a jet nozzle with electricity, and a vertical deflection electrode and a horizontal deflection electrode, etc. CONSTITUTION:Voltage from a DC voltage source 13 is impressed onto a charging electrode 12 only at the time of passing of ink drops to be used for printing. As a result, only the ink drops to be used for printing are charged with electricity, and the ink drops which are not to be used for printing are not charged with electricity. Thus charged ink drops are deflected in vertical direction by a vertical deflection electrode 14 and sent over to a horizontal deflection electrode 16. After a charged ink drop a was horizontally deflected in accordance with letters, etc., it is made to adhere onto a printing level B on a recording paper A. Further, a non-charged and unnecessary ink drop b is not deflected and made to go forward so that it is caught by a gutter 18.
