A nozzle check pattern is formed by ejecting liquid droplets onto a recording medium from a nozzle row formed in a liquid droplet ejection head. The nozzle check pattern includes: a first pattern formed by assigning consecutive numbers in order to the nozzles in the nozzle row, dividing the nozzle row into plural first nozzle groups, and ejecting predetermined dots onto the recording medium in order from the nozzle with the smallest number to the nozzle with the largest number in each of the first nozzle groups; and a second pattern formed by dividing the nozzle row into second nozzle groups whose number is larger than that of the first nozzle groups and ejecting predetermined dots onto the recording medium in order from the nozzle with the smallest number to the nozzle with the largest number in each of the second nozzle groups.
