Original Abstract Submitted
in an ink jet printing method for discharging ink from a liquid discharge head, the ink contains titanium oxide having a precipitation velocity of 1.0�10m/s or more based on a stokes equation in the ink, the liquid discharge head comprises a discharge port, a pressure chamber, an energy-generating element for discharging the ink, an upstream flow channel for supplying a liquid to the pressure chamber, a downstream flow channel communicating with the pressure chamber, and a pump communicating with the upstream and downstream flow channels and forming a circulation path in which the ink circulates in an order of the upstream flow channel, pressure chamber, downstream flow channel, and upstream flow channel, and a ratio of the flow rate q of the ink in the circulation path to the maximum cross-sectional area s of the circulation path, q/s [m/s], is higher than the precipitation velocity.
