INK JET HEAD, METHOD OF PRODUCING THE INK JET HEAD AND INK JET APPARATUS OPERABLE USING THE INK JET HEAD

摘要

An ink jet head comprises a plurality of ink liquid paths (102) in which energy generating elements are formed, a common liquid chamber (104) communicated with the plurality of ink liquid paths (102), and an air chamber (7) which is communicated with the common liquid chamber (104) via a communication section (8) formed at substantially a central portion of the air chamber (7) and which is formed along the longitudinal direction of the common liquid chamber (104). This arrangement of the ink jet head enables air in the air chamber (7) to act on refilling behavior of ink in each of the ink liquid paths (102) so that refilling in each of the ink liquid paths (102) is not delayed.
