Abstract:
1. An ink filling apparatus, for supplying ink to fill an ink tank that includes an ink storage chamber having a negative-pressure generation member, an ink supply port used to supply ink in the ink storage chamber to an outside, and a communication port through which the ink storage chamber is in fluid communication with the atmosphere, comprising: a pressure reduction unit configured to reduce pressure in the ink storage chamber to a predetermined pressure through the communication port; a filling unit configured to supply ink via the ink supply port to fill the ink storage chamber; and a cooling unit configured to cool down the ink present in a space in fluid communication with the ink storage chamber, wherein pressure in the space is reduced by the pressure reduction unit together with pressure in the ink storage chamber, the cooling unit cooling down the ink such that a saturation vapor pressure of the ink is lower than the predetermined pressure.
