  • 104 is a head side absorbing member provided for the recovery of recovery member for the ink discharge port portion 101 provided on the ink jet head unit 100, the details of which will be described later.
  • the ink storing portion has one and half or more the volume of the negative pressure generating member receiving portion, wherein the greater ink capacity is achieved by increasing the ratio of the ink storage to the volume of the ink storing portion of the ink vessel, as compared with the conventional constitution of the ink storing portion for storing the ink using only an ink absorbing member.
  • the ink supply from the ink storing portion 204 to the netative pressure generating member receiving portion 203 is carried out in response to pressure changes upon the ink consumption of the head unit (not shown).
  • the possibility of the ink flow passage formed in the ink concentrated portion can be further reduced, resulting in stabler ink distribution to collect the ink only near the ink supply port 209 more securely.

  • Fig. 6 shows an instance where the ink is filled in the ink jet cartridge of this embodiment.
  • the ink is held by the meniscus generating portion 213, and the ink is difficult to flow to the portion 205-1, so that the ink leakage from the atmosphere communicating port 208 is less likely to occur.
