ABSTRACT:
An ink jet recording apparatus for performing recording by ejecting ink to a recording medium, has a recording head and head driving unit. To effect ejection recovery, the head driving unit drives selected ejection energy generating elements in the recording head so that ink is ejected from orifices which correspond to the selected ejection energy elements. The selected orifices include at least one orifice adjacent to a particular orifice at which ink ejection recovery is performed, but exclude the particular orifice in an arrangement of the plurality of orifices. This ejection recovery technique efficiently removes bubbles from the particular orifice.
