ABSTRACT:
A main ink chamber for housing a capillary member and an intermediate ink chamber are provided, between which a first meniscus formation member is disposed. An ink guide member is in contact with the bottom face of the first meniscus formation member for supplying ink to the first meniscus formation member. The ink guide member is held by ink guide member retainers extending toward the ink guide member from a wall of a communication hole and is kept in contact with the first meniscus formation member. A larger number of the ink guide member retainers are placed on a side of the communication hole closer to a joint port than are placed on a side of the communication hole closer to the intermediate ink chamber. The placement of the ink guide member retainers guides bubbles entering the communication hole through the first meniscus formation member to the intermediate ink chamber to prevent bubbles entering the joint port and reaching the print head.
