ABSTRACT:
An ink storage unit used in an ink jet recording apparatus for recording by ejecting ink comprises a plurality of ink storage chambers, a plurality of movable walls and a mechanism for holding each of the movable walls. Each of the ink storage chambers stores ink. Each of the movable walls is provided in the each ink storage chamber respectively so as to seal stored ink against air, and each movable wall can move according to a change of amount of ink in each ink storage chamber. The mechanism for holding the movable walls exerts a force opposed to a force which is exerted on the each movable wall according to the change of amount of ink, on each of the movable walls so as to make the pressure in each ink storage chamber an appropriate negative pressure.
