ABSTRACT:
In a structure of an ink tank having a deformable sheet that constitutes the tank and a spring for imparting a negative pressure, unstableness of the negative pressure attributable to the deformation of the sheet as a result of ink consumption is prevented. For this purpose, a plate-like member is joined to a top section of the sheet formed in a convex shape, and the spring for generating the negative pressure in the tank is mounted to the same member. This makes it possible to maintain a high volume ratio of the ink tank and to achieve stableness of the negative pressure by adequately regulating the deformation of the sheet when the sheet is displaced in the direction of retracting toward the interior of the tank as a result of a reduction of the amount of ink in the tank.
