Abstract

PURPOSE:To improve quality of printed letter, by varying jetting pressure of ink jet particle on the basis of signal selected in accordance with the kind of image. CONSTITUTION:When a solenoid valve 9 is open, pressure is applied to ink in an ink jet head 1 by an ink compressing pump 7, and at the same time, the ink is jetted out from the ink jet head 1 by exciting it by means of an electrostrictive oscillator, etc. A column of jetted out ink is separated into ink drops at a charging electrode 2, electric charges are selectively given to thus separated ink drops in accordance with printing information signals from a letter-printing signal generator, thus charged ink drops are deflected by a deflecting electrode 2 in accordance with amounts of charge and information is recorded on a recording paper 4. On the other hand, noncharged ink drops which are not used for printing are captured by a gutter 5 and recovered into an ink tank 6 for reutilization.
