ABSTRACT:
In an ink jet type head assembly, a plurality of auxiliary electrodes alternate with a plurality of ejection electrodes. A voltage of the same polarity as charge deposited on toner particles is applied to two of the auxiliary electrodes adjoining an ejection electrode which should eject ink. This successfully prevents the toner particles from migrating toward the auxiliary electrodes away from the ejection electrode.
