Image recording apparatus

An image recording apparatus comprising:

• a liquid-ejection head in which formed a plurality of liquid-ejection openings which are arranged in a first direction and through each of which liquid is ejected onto a recording medium;
• a moving mechanism configured to move the recording medium relative to the liquid-ejection head in a second direction which is perpendicular to the first direction;
• a drive-data storage portion configured to store drive data based on which the liquid-ejection head is driven;
• a drive-data converting section configured to convert the drive data such that an image position adjustment in which a position of an image formed on the recording medium by the liquid ejected from the liquid-ejection head on the basis of the drive data which has been converted is changed in the first direction with respect to an image formed on the recording medium by the liquid ejected from the liquid-ejection head on the basis of the drive data which has not been converted;
• a first ejection-opening extracting section configured to extract at least one liquid-ejection opening whose number of ejections of the liquid during the recording of the image on at least one recording medium of a first predetermined number on the basis of the drive data which has not been converted by the drive-data converting section is smaller than a second predetermined number among the plurality of liquid-ejection openings;
• a second ejection-opening extracting section configured to extract at least one liquid-ejection opening whose number of ejections of the liquid during the recording of the image on at least one recording medium of a third predetermined number on the basis of the drive data which has been converted by the drive-data converting section is smaller than a fourth predetermined number among the plurality of liquid-ejection openings, the recording of the image being performed successively before or successively after the recording of the image on the at least one recording medium of the first predetermined number;
• and
• an ejection controller configured to control the ejection of the liquid from the liquid-ejection head such that at least one preliminary ejection of the liquid from at least one liquid-ejection opening extracted by both of the first ejection-opening extracting section and the second ejection-opening extracting section is performed upon recording of the image on at least one of a plurality of the recording media which is subjected to both of the recording of the image on the at least one recording medium of the first predetermined number on the basis of the drive data which has not been converted by the drive-data converting section and the recording of the image on the at least one recording medium of the third predetermined number on the basis of the drive data which has been converted by the drive-data converting section.
