The present invention provides an ink jet recording apparatus which can prevent problems such as image defects caused by shortage of ink, and decreases in the printing speed from occurring. When execution of a print job is instructed, a printing processing for the print job is started. The number of pixels which have been actually printed is added to a current pixel count C1, and it is determined whether or not the print job is finished. When it is determined that the print job is finished and the pixel count C1 exceeds a predetermined number of pixels X1, an ink supply unit is controlled so that ink of a predetermined proportion A (%) of the amount of ink used, which amount corresponds to the pixel count C1, is supplied to a sub-ink tank.
