Abstract
There is disclosed an apparatus for restoring an ink jet recording head which can securely recover the ink jet recording head from the ink non-ejection condition caused by foreign particles or bubbles adhering inside the ink passage of an ejecting nozzle and which can prevent unnecessary bubbles from generating in the ink jet recording head. In the restoring operation, in which foreign particles are discharged together with ink from the ejecting nozzle by pressurizing the ink in an ink tank, an inner pressure of an ink supply passage is adjusted to reach a set pressure value.
