ABSTRACT:
In a recording apparatus in which ink is supplied to a head from a main tank via a sub-tank, when ink is supplied to the sub tank from the main tank, the ink is first supplied to a flow path connected to the sub-tank, and then ink is supplied into an ink absorber accommodated within the sub-tank via a filter being in contact with the absorber. The flow path is located between the ink absorber and the head. The ink is supplied into the sub-tank from the main tank in the reverse direction of the flow path for supplying ink to the recording head from the absorber during ink ejection. As a result, after ink is supplied to the sub-tank from the main tank, ink portions contained in the ink absorber and the filter are united into one continuous portion, so that a recording apparatus preventing the failure of ink supply due to ink discontinuity can be provided.
