Abstract

PURPOSE:To remove unstability due to ink contamination by alternately applying phase retrieval charging pulses of different phases from each other to charging electrodes in the prescribed period and detecting the discharging current flowing through a conductive gutter. CONSTITUTION:An ink injected from a head 5a is isolated into ink particles at a position advanced at the prescribed distance, a charging electrode 6 is disposed at the isolated position, and when a charging voltage is applied to the electrode 6 at the isolating time point, the ink particles are charged in the polarity opposite to the charging voltage polarity. A gutter 9 is a conductor, and is secured to a gutter holder 13 of the insulator. One end of the core wire of a shielded wire 15 is connected to the gutter 9, and the other end is connected to a charge detector 20. When phase retrieval charging pulses of different phases from each other are alternately applied to charging electrodes 6, a noise can be removed, and a stable charge can be detected.
