Abstract

In an ink jet recording head, an ink pool has a main flow path communicating with an ink supply port and a plurality of branch flow paths branching from the main flow path. Each ejector has a pressure chamber, a pressure generating unit and a nozzle. The pressure chamber communicates with the corresponding one of the branch flow paths. The pressure generating unit generates a pressure wave in ink charged into the pressure chamber. The nozzle ejects the ink from the pressure chamber compressed by the pressure wave. At least one wall surface forming each of the branch flow paths is formed of a damper member elastically deformable in accordance with the change of pressure in the branch flow path.
