ABSTRACT:
An ink cartridge for storing ink includes a thermal ink-jet head provided with a heating portion that generates thermal energy for discharging the ink. The heating portion has, on its surface in contact with the ink, a protective layer containing at least one of a silicon oxide, a silicon nitride, and a silicon carbide. The ink contains a substance that dissolves the protective layer and a compound represented by the following formula (1), and the content X (% by mass) of the compound of the formula (1) satisfies a relationship of 1≦X≦30: Formula (1) R1-A-R2, wherein A represents one selected from —S—, —S(═O)—, and —S(═O)2—, and R1and R2each independently represent a group selected from a hydrogen atom, a hydroxyl group, an alkyl group, a hydroxyalkyl group, an alkenyl group, an acyl group, a carbamoyl group, a carboxyl group, and a sulfonyl group.
