Abstract:
1. An inkjet recording apparatus comprising: at least one recording head unit having a plurality of nozzle lines each having a plurality of nozzles driven with multi-phase drive; a moving unit to move the recording head unit by predetermined times in a main scanning direction crossing the nozzle lines in an area facing one same recording area on a recording medium; a clock generating unit to generate clock signals using an electric signal generated according to moving amount of the recording head; and a recording head control section to control the recording head unit, the recording head control section including a phase control section to control each drive phase of the plurality of nozzle lines on the basis of the clock signals, and the phase control section comprises phase setting units to switch the drive phases of the plurality of nozzle lines in predetermined phase orders in synchronization with the clock signals; wherein the recording head control section controls the recording head unit such that, by driving the nozzle lines with the drive phases controlled by the phase control section during movement of the recording head unit by the moving unit, an image is recorded with a plurality of pixels reduced by a predetermined reduced pattern in the main scanning direction, and with predetermined times of repetition of this recording, an image recording in the recording area is completed.
