<P>PROBLEM TO BE SOLVED: To provide a liquid ejection head capable of more surely suppressing the fluctuations of the pressure in a flow path in the liquid ejection head. <P>SOLUTION: A recording head introduces ink into a reservoir 27 from an introduction port 35, through an ink introduction path 25 from the introduction part of an ink introduction needle 23, to supply the ink to a pressure chamber 29 from the reservoir through an ink supply port 28. In the recording head, the reservoir includes a gas storage part 26 above the introduction port 35 and the ink supply port 28 in a vertical direction, gas in the ink introduction path is introduced into the gas storage part and the fluctuations of the pressure in the ink introduction path are reduced by the elastic deformation of the introduced gas. <P>COPYRIGHT: (C)2013,JPO&INPIT |
