The ink tank unit has a partition portion for partitioning between an ink storing portion for storing the ink to be supplied to the ink jet head unit and a negative pressure generating member receiving portion having a negative pressure generating member. The ink supply port is provided on the negative pressure generating member receiving portion. And the partition portion has an ink communicating portion at an end portion of the partitioning portion on the side of the negative pressure generating member receiving portion where the ink supply port is provided, and makes contiguous the ink storing portion and the negative pressure generating member receiving portion in a movement direction of the ink tank unit when discharging the ink. <IMAGE>
