摘要:
An ink jet recording head comprises an ink discharging opening, a liquid pathway communicating with the ink discharging opening, a device for generating energy used to discharge ink provided along the liquid pathway, a first liquid chamber communicating with the liquid pathway, a second liquid chamber communicating with the first liquid chamber and provided only on the side of the liquid pathway opposite to the side on which the device for generating energy is provided and a pipe feeds ink to the second liquid chamber. A bag in the second liquid chamber forms a flexible space filled with air for absorbing each pressure fluctuation created in the first liquid chamber by actuation of the energy generating device and for preventing such fluctuation from propagating to the ink feeding pipe.
