Inkjet recording apparatus and inkjet recording method

An inkjet recording apparatus, comprising:

• a plurality of recording heads each having at least a nozzle array from which droplets of an ink are discharged;
• a pair of units for subsequent treatment that apply an energy to the droplets discharged from the plurality of recording heads onto a recording medium to exercise subsequent treatment for dots formed with the ink;
• and
• a controller that, while reciprocating the plurality of recording heads along a first direction, prompts the plurality of recording heads to discharge the droplets onto the recording medium at timings of forward and backward scans being performed in order to obtain an image formed with the dots on the recording medium,
• wherein two or more than two of the plurality of recording heads being disposed in a staggered arrangement in the first direction and a second direction intersecting the first direction,
• the pair of units for subsequent treatment being disposed along the second direction and spaced at an interval with the plurality of recording heads being interposed therebetween,
• a respective one of the pair of units for subsequent treatment having a length in the second direction greater than or equal to an ink-dischargeable extent in the second direction of the plurality of recording heads in one scan, and
• two or more than two nozzle arrays of the plurality of recording heads, from which droplets of a same color ink are discharged, being disposed symmetrically with respect to an intermediary line extending along the second direction and passing through center of the interval between the pair of units for subsequent treatment that are spaced apart.
