摘要：PROBLEM TO BE SOLVED: To provide an ink jet printer which can obtain an image quality of an image which is not pale as compared with a case without a defective nozzle by suppressing deterioration of the image quality of the image recorded on a recording medium when a normal nozzle alternatively discharges to the defective nozzle.SOLUTION: An ink jet printer records on a recording medium by a plurality of paths where a nozzle of a recording head is divided into a plurality of blocks. When a nozzle in a different block corresponding to a position of a defective nozzle replaces and records alternatively, a new discharge rate of an alternative nozzle is calculated by dispersing a discharge rate of the defective nozzle on the basis of a discharge rate when the nozzle is not replaced. Recording is carried out by using the new discharge rate when the alternative nozzle alternatively records to the defective nozzle. Thus, deterioration of an image quality is suppressed and a high-quality image recorded on the recording medium can be obtained.
