Abstract
A joint part of an ink tank has a connection part capillary member. A filter is placed at the tip of an ink introduction part on the side of a recording head. The ink tank is connected by bringing a face of the filter into contact with the connection part capillary member; liquid connection is made without entry of air. At this time, a force of pressing the connection part capillary member against the inside of the ink tank occurs. However, since the connection part capillary member is provided with a presser part on the rear side, the presser part absorbs the press pressure and the contact state is stable, preventing the connection part capillary member from being detached to the inside of the ink tank. Additionally, the ink tank has a seal material for sealing the ink supply hole in a state in which the tank joint part is detached from the recording head joint part.
