Patent ID: 8201917

Claim:
An inkjet recording apparatus that forms an image corresponding to an image data on a recording medium, the inkjet recording apparatus comprising: a flow path unit comprising a discharge port that is configured to discharge ink and an ink flow path that is configured to supply the ink to the discharge port; an actuator that is configured to supply discharge energy to the ink in the ink flow path to be discharged from the discharge port and non-discharge energy to the ink in the ink flow path, wherein the non-discharge energy is adjusted not to discharge the ink from the discharge port; a drive controller that is configured to cause the actuator to supply the discharge energy to the ink to discharge the ink onto the recording medium; a cap that is configured to move between a covering position and an open position, wherein when the cap is at the covering position, the cap covers the discharge port, and wherein when the cap is at the open position, the discharge port is uncovered; and a cap moving unit that is configured to move the cap between the open position and the covering position; wherein, after the image data begins being supplied, the drive controller causes the actuator to supply the non-discharge energy to the ink in both a first period and a second period, wherein the first period begins at a starting of the supply of the non-discharge energy, and the second period begins at the end of the first period and ends when the supply of the discharge energy is started, wherein a frequency of the supply of the non-discharge energy during the first period is greater than the frequency of the supply of the non-discharge energy during the second period.
