Abstract: A liquid ejection head includes nozzles, separate chambers, a common chamber, inlet portions, a filter unit, and ribs. Droplets of liquid are ejected from the nozzles. The separate chambers are communicated with the nozzles. The inlet portions are communicated with the corresponding separate chambers. Liquid is supplied from the common chamber to the separate chambers through the inlet portions. The filter unit is disposed between the inlet portions and the common chamber to filter liquid in an area across the separate chambers in a first direction in which the nozzles are arrayed. The ribs are disposed in the filter unit at intervals corresponding in size to at least two of the separate chambers in the first direction to partition the filter unit. The inlet portions are communicated in the first direction with each other in at least one portion of each of the inlet portions facing the filter unit.

Abstract: An ink jet printing apparatus includes an ink jet head having a plurality of nozzles for respectively ejecting ink drops, a plurality of ink chambers communicating with the nozzles, and a plurality of electromechanical conversion elements corresponding to the respective nozzles. The volume of the ink chamber of the non-drive channel is increased by the influence of the drive channel adjacent thereto, and thereby undesired ejection of the ink drop occurs. To solve this problem, a drive energy set for ejecting the ink drop is applied to the piezoelectric elements of the drive chambers n−1, n+1 and a reduced drive energy set for not ejecting the ink drops is applied to the piezoelectric element of the non-drive channel n.
