Zusammenfassung:An ink supplier includes a supply reservoir 22 that stores ink to be supplied to a plurality of heads in an ink-jet printing apparatus. The supply reservoir 22 includes: a first horizontal reservoir 51 of a cylindrical shape having a plurality of supply ports communicating with a plurality of heads; and a first vertical reservoir 52 having a side surface provided with a first opening 520 directly or indirectly communicating with one end 51a of the first horizontal reservoir 51. A top surface of the first horizontal reservoir 51 is tilted from a horizontal direction at an angle of tilt equal to or greater than 0.3° in such a manner as to extend upward from the other end 51b toward the first opening 520 or the one end 51a. Thus, air bubbles in the first horizontal reservoir 51 move along the top surface into the first vertical reservoir 52 through the first opening 520. As a result, it becomes possible to remove air bubbles from the inside of the first horizontal reservoir 51 without providing a pipe for removal of air bubbles that might be a cause for agglomeration. Specifically, it is possible to remove air bubbles in a reservoir while suppressing agglomeration of ink.
