Abstract: PURPOSE:To reduce the charge circuit and wiring by for example, printing two colors in forward way and printing the remainder two colors in return way, by a method wherein several charge electrodes are commonly connected as one group and connected to one charge control circuit. CONSTITUTION:When the data of cyan and yellow are set from an input part 8, a print direction indication part 9 turns ON electromagnetic valves 16a and 16c and jet out the ink of yellow and cyan, turns OFF electromagnetic valves 16b and 16d and stops the jetting of the ink of magenta and black. At that time, because the outputs of charge circuits 12-1 and 12-2 are connected parallel to the charge electrodes 15a and 15b, and 15c and 15d of yellow and magenta, and cyan and black, magenta and black are never accidentally printed. Then, on the return way, the print direction indication part 9 turns OFF the electromagnetic valves 16a and 16c and jet out the ink of magenta and black. Thus, without exclusive exchanging circuit or the like, the wiring of charge circuit can be reduced to one half.
