INK JET RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To surely collect by causing U-turn of ink particles for spare discharge in an ink jet head wherein ink particles for spare discharge are made to make U-turn for collection while spare discharge effect is maintained. SOLUTION: An ink jet recording device comprises a first chargedeflection signal forming means for generating a first charge pulse of a charging deflection signal when a spare discharge signal works to discharge ink particles for spare discharge from nozzle holes, and a second charge deflection signal forming means for generating a second charge pulse of the charge deflection signal when a recording signal works to discharge ink particles for recording from the nozzle holes.
