Image recording device

An image recording device comprising:

• a maintenance mechanism that conducts, according to a print job, maintenance for maintaining and recovering an ink ejection function of a recording head that conducts a printing process on a print medium;
• and
• a maintenance mechanism control unit that defines, as a cumulative number, a number of print media on which the printing process has been conducted after previous maintenance was conducted, that presets a lower limit and an upper limit of the cumulative number for determining whether or not to conduct the maintenance, and that makes the maintenance mechanism conduct the maintenance in accordance with a result of comparing the cumulative number estimated for the printing process based on the print job with the lower limit and the upper limit,
• wherein the maintenance mechanism control unit makes the maintenance mechanism conduct the maintenance before start of printing of the print job when priority on image quality, which requires high quality printing, is set in the print job, when the cumulative number is less than the lower limit before the print job starts, and when the cumulative number is estimated to reach the lower limit during the printing process.
