An inkjet recording apparatus comprising: a recording head configured to eject ink; an ink tank configured to store ink to be supplied to the recording head ; a supply flow path (C2) configured to supply ink from the ink tank to the recording head ; a supply pump (P1) located in the supply flow path (C2) and configured to pump ink in the supply flow path (C2); a collection flow path (C4) configured to collect ink from the recording head and supply the collected ink to the ink tank ; a collection pump (P2) located in the collection flow path and configured to pump ink in the collection flow path; a relief flow path (C3) connecting a first position in the supply flow path (C2) to a second position in the supply flow path (C2), wherein the first position is located at a downstream side of the supply pump (P1) in the supply flow path (C2) and the second position located at an upstream side of the supply pump (P1) in the supply flow path (C2); and a differential pressure regulating valve (V3) located in the relief flow path (C3) and configured to, in a case where the pressure of the pumped ink in the supply flow path (C2) is larger than a predetermined value, open the relief flow path (C3) so as to allow ink in the supply flow path (C2) to flow from the first position to the second position characterized in that the supply pump (P1) is configured to provide a first predetermined amount of ink flow in the supply flow path, and the collection pump (P2) is configured to provide a second predetermined amount of ink flow in the collection flow path irrespective of an amount of ink to be ejected from the recording head. a recording head configured to eject ink; an ink tank configured to store ink to be supplied to the recording head ; a supply flow path (C2) configured to supply ink from the ink tank to the recording head ; a supply pump (P1) located in the supply flow path (C2) and configured to pump ink in the supply flow path (C2); a collection flow path (C4) configured to collect ink from the recording head and supply the collected ink to the ink tank ; a collection pump (P2) located in the collection flow path and configured to pump ink in the collection flow path; a relief flow path (C3) connecting a first position in the supply flow path (C2) to a second position in the supply flow path (C2), wherein the first position is located at a downstream side of the supply pump (P1) in the supply flow path (C2) and the second position located at an upstream side of the supply pump (P1) in the supply flow path (C2); and a differential pressure regulating valve (V3) located in the relief flow path (C3) and configured to, in a case where the pressure of the pumped ink in the supply flow path (C2) is larger than a predetermined value, open the relief flow path (C3) so as to allow ink in the supply flow path (C2) to flow from the first position to the second position characterized in that the supply pump (P1) is configured to provide a first predetermined amount of ink flow in the supply flow path, and the collection pump (P2) is configured to provide a second predetermined amount of ink flow in the collection flow path irrespective of an amount of ink to be ejected from the recording head. <EOS>
