1. A liquid discharge apparatus for forming an image on a recording medium, the liquid discharge apparatus comprising:
a head including a plurality of nozzle rows in each of which a plurality of nozzles for discharging liquid are arranged in a predetermined direction, wherein the plurality of nozzle rows comprises three or more nozzle rows configured to discharge colored ink liquid,
processing circuitry configured to:
detect landing positions of the liquid discharged from the plurality of nozzle rows on the recording medium; and
correct the landing positions of the liquid based on a result of detecting the landing positions of the liquid; and
a memory configured to store data related to a relation among the landing positions of the liquid discharged from the plurality of nozzle rows,
wherein the processing circuitry is configured to detect landing positions of the liquid discharged from one representative nozzle row among the plurality of nozzle rows, and
wherein the processing circuitry is configured to correct landing positions of the liquid discharged from all of the plurality of nozzle rows based on a result of detecting the landing positions of the liquid discharged from the one representative nozzle row and the data related to the relation among the landing positions stored in the memory.
