Abstract
An inkjet recording apparatus, which can enhance the reliability of the phase search result to detect the optimal timing when the ink particles are electrically charged by the electrification electrode and secure the stable printing quality, is provided. The inkjet recording apparatus includes an ink receptacle in which a printing ink for an object to be printed is received; a nozzle which is connected to the ink receptacle and from which the ink fed under pressure is discharged; an electrification electrode to make ink particles discharged from the nozzle electrically charged; an electrification signal generation unit to generate an electrification signal to make the electrification electrode electrically charged; deflection electrodes to make the ink particles electrically charged by the electrification electrode deflect; a gutter to recover the ink unused for the printing; and a control unit to control operations of the inkjet recording apparatus as a whole; a first electric charge detection section to detect an amount of electric charge in accordance with the electrically charged ink particles between the electrification electrode and the deflection electrodes; and a second ele…
