    • PROBLEM TO BE SOLVED: To provide a recording liquid for use in record on an object, liquid cartridge of filling the liquid, liquid-discharging cartridge for discharging the liquid onto the object, device and method for discharging the liquid, preventing an ink from non-discharge. SOLUTION: The ink 2 contains a hydrophobic colloid which normally has zeta potential of at most +10 mV, and when the pH of the ink 2 becomes 4-6, the zeta potential is charged to positive. Thereby elusion of silicon, silicon compounds, etc. into the ink 2 from a circuit board 42 composed of a silicon wafer etc., and deposition of the colloid onto a heating resistor 46 of negatively being charged, are suppressed, preventing causing of kogetion on the heating resistor 46 and non-discharge of the ink by clogging resulting from precipitation thereof in an ink passage 32 and in a nozzle 43a.
