Abstract: An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.
