Abstract: There is provided a liquid supply apparatus eliminating the need for a power supply, having relatively light weight and small footprint, and ensuring a stable liquid supply. The liquid supply apparatus includes a first support member, a second support member, a balloon having one end supported by the first support member and the other end supported by the second support member, and a casing having a constant longitudinal length. The balloon is disposed in the casing and is configured so as to be able to hold a liquid therein and discharge the liquid therefrom. When the balloon holds the liquid, the one end and the other end of the balloon are positioned in the case.

Abstract: A non-water-based inkjet ink containing a colorant, is characterized in that a mixed solvent having a solubility parameter value of from about 8 to about 10 is used as a solvent. The ink is an inkjet ink of which solvent hardly erodes a head member so as to allow long term stable printing and also hardly penetrates the material of media so as to improve the printing quality.

Abstract: An inkjet ink containing a colorant, where an amine compound is added as a pH adjuster. The ink is capable of preventing the pH of the ink from being shifted to the acidity side due to corrosive substances (e.g., acid substances) generated by deterioration of ink, adverse effects due to water absorption and moisture absorption, or degradation of resin (e.g., degradation of vinyl chloride-vinyl acetate copolymer resin), thus preventing erosion of a head nozzle member.

Abstract: An inkjet ink is provided containing a colorant and using vinyl chloride-vinyl acetate copolymer resin, and characterized in that a stabilizer for preventing the vinyl chloride-vinyl acetate copolymer resin in the inkjet ink from being degraded with age is added. An inkjet ink is provided using VCVAC resin which is capable of preventing the VCVAC resin from being degraded and thus preventing increase in viscosity thereof.
