PROBLEM TO BE SOLVED: To reduce or eliminate a pressure wave coming through a common ink storage which gives an effect on an ink drop jetting from an adjacent ink jet hole in jetting ink, principally as to a printhead of ink jet type. SOLUTION: A pressure wave can be reduced or eliminated by consuming energy before the pressure wave reaches a common ink storage by providing a pressure releasing chamber between the common ink storage and an ink pressurizing chamber.
