Abstract
An ink jet recording method uses an ink jet recording apparatus equipped with a line head that includes a plurality of recording element substrates each having a nozzle array comprised of a plurality of nozzles, which eject an aqueous ink, arranged in a predetermined direction. The recording element substrates are arranged in the predetermined direction such that each of the recording element substrates constitutes an overlapping portion at which a terminal portion of the recording element substrate is overlapped with a terminal portion of an adjacent recording element substrate in the predetermined direction. The method includes setting the average temperature To (° C.) of an ink ejected from overlapping-portion nozzles included in the overlapping portion of the nozzle array and the average temperature Tc (° C.) of an ink ejected from the center-portion nozzle included in the center portion of the nozzle array so as to satisfy the relationship Tc>To.
