Abstract
An ink jet recording apparatus includes an ink composition, an ink encasement in which the ink composition is encased, a recording head that ejects the ink composition, and a carriage configured to move the recording head back and forth. The carriage carries the ink encasement, with the ink encasement integrated with the carriage. The ink encasement has an ink fill port that opens and shuts as a port through which the ink composition is loaded. The ink composition contains a water-soluble dye and a polyhydric alcohol with a normal boiling point of 270° C. or above, with the percentage of the polyhydric alcohol being 26.0% by mass or less of the total amount of the ink composition.
