Abstract:
1. An inkjet recording apparatus comprising: a nozzle head configured to eject ink droplets; a deflecting voltage controller configured to generate a recording signal corresponding to recording information; a charging voltage controller configured to charge the ink droplets on the basis of the recording signal; and a deflecting unit including a first deflecting electrode and a second deflecting electrode opposed to each other, the charged ink droplets being made incident between the first deflecting electrode and the second deflecting electrode, the first deflecting electrode having a polarity the same as an electric polarity of the charged ink droplets, at least a part of the first deflecting electrode inclining with respect to an extended line in an ink droplet incident direction of the ink droplets made incident between the first deflecting electrode and the second deflecting electrode such that a space between the part of the first deflecting electrode and the extended line gradually increases, and the second deflecting electrode having a polarity opposite to the electric polarity of the charged ink droplets and deflecting the charged ink droplets, wherein an entire electrode surface of the first deflecting electrodes inclines such that the space between the electrode surface of the first deflecting electrode and the extended line in the ink droplet incident direction gradually increases, and wherein an electrode surface of the second deflection electrode is parallel to the electrode surface of the first deflecting electrode.
