Ink jet recording apparatus and method

摘要

An ink jet recording apparatus comprises an ejection orifice for ejecting an ink, a supply portion, communicating with the ejection orifice, for supplying an ink stored therein to the ejection orifice, an ejection energy producer, arranged in the supply portion, for applying energy for ink ejection to the ink, a pressure producer, arranged in the supply portion at a position different from the ejection energy producer, for producing a pressure wave in the supply portion, and a controller for controlling the pressure producer to produce a pressure wave different from a pressure wave produced in the supply portion by the ejection energy producer.
