Abstract
In an ink jet printer of the type wherein an ink jet nozzle continuously ejects the train of ink droplets and only ink droplets which are directed towards a recording surface are electrically charged and deflected by a pair of deflection electrodes so as to dot-form a character, a pair of auxiliary or compensation electrodes are provided in order to eliminate or control the inclination relative to the vertical line of dot-formed characters due to the relative speed between the recording surface and the ink jet nozzle.
