Abstract
An ink jet printer comprises a plurality of print heads 23, 23' respectively communicating with interiors of mutually different ink tanks Tk, Ty, Tm, and Tc and each having an ink nozzle for ejecting ink accommodated in each of the ink tanks Tk, Ty, Tm, and Tc onto a printing surface, wherein the position of a distal end of the ink nozzle having a higher velocity of an ink droplet ejected from the distal end of the ink nozzle is disposed at a position apart farther from the printing surface than the position of a distal end of the ink nozzle having a lower velocity of the ink droplet, so as to reduce variations in a timing when the ink droplet ejected from each of the ink nozzles reaches the printing surface.
