A control portion makes a recording head perform flushing processing every time a flushing area that does not overlap a recording medium faces the recording head but makes the recording head perform no flushing processing when a flushing area that at least in a part of it overlaps a recording medium faces the recording head. The longer a non-flashing period between the previous and present sessions of flushing processing, the larger the control portion makes the amount of ink ejected by each of nozzles in the present session of flushing processing.
