This aims to provide an inkjet recording apparatus which prevents a beading or a color bleeding in a recording system using a line head, and an inkjet recording method. The inkjet recording apparatus comprises an ink line head equipped with nozzle rows having a plurality of nozzles arranged at a predetermined pitch for discharging inks containing coloring materials, and a fixing liquid line head equipped with nozzle rows having a plurality of nozzles arranged at a predetermined pitch for discharging fixing liquids to enhance the fixtures of the inks to a recording medium. The inkjet recording apparatus performs the records by discharging the inks and the fixing liquids from the individual line heads to the recording medium while moving the recording medium and the individual line heads relatively in predetermined directions. The inkjet recording apparatus is characterized in that the nozzle rows of the ink line head and the fixing liquid line head are arranged such that they are deviated from each other by one half of the predetermined pitch in the nozzle row direction.
