ABSTRACT:
Inks are supplied from ink inflow flow passages to ink storage chambers in a subtank. The inks are further supplied from the ink storage chambers via ink outflow flow passages to a head. The ink storage chambers are stacked in the vertical direction, with upper surfaces or lower surfaces thereof being defined by damper films respectively. Parts of upper surfaces of the ink inflow flow passages and parts of upper surfaces of the ink outflow flow passages are defined by gas-permeating films. The gas, which is contained in the liquids in the ink inflow flow passages and the ink outflow flow passages, is discharged via the gas-permeating film to a gas discharge passage. The gas is prevented from the outflow together with the liquids from the liquid supply apparatus.
