摘要： Provided is a liquid ejecting head including a plurality of substrates that are at least partially bonded to one another with adhesives and form a liquid passage in which a liquid flows. The liquid passage includes a pressure-generating chamber that communicates to a nozzle opening through which the liquid is ejected. The adhesive being exposed to a wall surface of the passage on the upstream side of the pressure-generating chamber is composed of a first adhesive, and the adhesive being exposed to a wall surface of the downstream-side passage including the pressure-generating chamber is composed of a second adhesive. The second adhesive has affinity with the liquid higher than that of the first adhesive.

摘要： The ink jet type printer is equipped with a recording head for ejecting ink including humectant and water from a nozzle formed on a nozzle forming surface and a cap which can seal the nozzle forming surface of the recording head. Further, the ink jet type printer is equipped with a control section for detecting an amount of the ink discharged into the cap from the nozzle, for calculating an available water amount which is a water amount except water absorbed by humectant in the ink in the cap based on the detected ink amount, and for performing maintenance control for forcibly discharging ink into the cap from the nozzle so that the amount of the ink discharged from the nozzle becomes smaller when the calculated available water amount is large than when small.
