Abstract
A confrontation type charging electrode member is disposed below or above flying paths of ink drops generated by a multi-nozzle jet in order to charge the ink drops in a binary type multi-nozzle ink jet printer. The electrodes apply a guard voltage to guard drops in front of and behind as well as on each side of printing drops so that the printing drops can move straight thereby reducing cross-talk between drops.
