Abstract
An ink jet recording apparatus for performing recording using a recording head for ejecting an ink from a plurality of ejection orifices, includes a print control unit for performing a print operation while switching a print mode between a thin multi-pass print mode for sequentially recording divided recording data in a plurality of number of times of relative scan operations of the recording head with respect to a single recording area, and a 1-pass print mode for recording all recording data in a single relative scan operation of the recording head, and an eject quantity control unit for controlling the eject quantity of the ink ejected form the recording head so that a total ink quantity on the recording area in the thin multi-pass print mode is larger than a total ink quantity in the 1-pass print mode.
