Ink jet printer

摘要

An ink jet printer in which ink particles separated from an ink jet at positions shifted from the normal charging electrode position are maintained charged at all times thereby preventing the separated particles from reaching the recording medium and being displaced thereon as moise. Auxiliary charging electrodes are provided adjacent the charging electrodes which control the charging of the ink particles according to a printing signal. The auxiliary charging electrodes can be provided as first and second sets of electrodes disposed on either side of the charging electrodes or as a continuous set of plates running from a position near the nozzles past the charging electrodes.
