An ink ejection nozzle constituting section characterized for performing printing with a high image quality, and an ink ejection nozzle constituting section characterized for performing full-color printing at a high speed are separately disposed in one ink jet head to constitute a recovery system capable of performing suction recovery only in each of the constituting sections, and the suction recovery optimized for each constituting section is carried out. Accordingly, the size enlargement of a recording apparatus can be restrained, and total ink consumption can be suppressed at the time of maintenance.
