摘要： An inkjet recording apparatus comprises an inkjet recording head, an ink-testing unit having an ink-test chamber, a pressure-vibration generating unit that generates a pressure vibration in the ink-test chamber, a pressure-vibration detecting unit that detects the pressure vibration, an ink inlet that introduces ink into the ink-test chamber and an ink outlet through which ink is discharged from the ink-tester chamber. Failures of ink ejection can be prevented by detecting cavitation cores by the ink-test chamber and removing ink containing the cavitation cores from ink supplied to the inkjet recording head.
