An ink jet recording apparatus includes a recording head having a plurality of discharge ports for discharging ink supplied from an ink tank and a plurality of heating elements. The ink jet recording apparatus further includes a detection unit configured to detect a remaining amount of ink in the ink tank, and a preliminary discharge unit configured to discharge ink from the discharge ports, unrelated to recording, by applying energy to the heating elements for recovering the recording head. The ink jet recording apparatus performs control so that when the remaining amount of ink detected is less than a predesignated remaining amount of ink, energy applied to the heating elements per unit time by the preliminary discharge unit is smaller as compared with energy applied to the heating elements per unit time when the remaining amount of ink is more than or equal to the predesignated remaining amount of ink.
