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