ABSTRACT:
The present invention is to provide an on-demand type ink-jet printer which is free from the risk such that the nozzle is stopped and which is also free from the maintenance. An ink-jet print head comprises a liquid chamber (2) into which a carrier liquid (7) is filled, ink-jet driving means (3), (4) disposed within the liquid chamber (2), a nozzle (14) communicated with the liquid chamber (2) and a mixing unit (14a) disposed in the vicinity of the nozzle (14) for mixing an ink (9) into the carrier liquid (7). The ink (9) is mixed into the carrier liquid (7) in the liquid chamber (2) by the mixing unit (14a), pressed by the ink-jet driving means (3), (4) and then ink-jetted from the nozzle (14). Since the carrier liquid (7) is constantly filled into the nozzle (14), the nozzle (14) can be prevented from being choked up.
