Abstract
An ink container includes an ink containing unit having a housing which directly contains ink, an ink guide, a movable member changing the internal volume of the ink containing unit, and a buffer chamber. The buffer chamber allows changing the internal volume of the ink containing unit when the movable member moves, and has an air communicating portion and is defined by a wall structure. A negative pressure controlling mechanism for controlling the negative pressure in the ink containing unit generated when the ink is guided out of the ink containing unit is provided apart from the housing.
