Abstract
A nozzle discharge quantity correction method includes performing correction quantity calculation as the number of the nozzle array units in stages such that a total sum C of the weight of droplets in nozzle array units after correction and the weight of the droplets in other nozzle array units in which discharge is performed on the discharge region becomes a previously set predetermined quantity B based on the difference between the total sum A of the weight of all the droplets discharged to a discharge region when the weight of the droplets discharged from a nozzle are not corrected and the predetermined quantity B.
