    摘要: Provided is an ink including water, an organic solvent, resin particles, and a thickener. The thickener comprises polymer particles having a carboxylic acid structure. A proportion of the thickener in the ink is 0.05% by mass or more. Change in viscosity of the ink between before and after storage of the ink at 70° C. for 1 week is 20% or less. The change in viscosity is expressed by Formula (1): Change in viscosity (%)=[(a−b)/b]×100 . . . Formula (1), where a represents a viscosity (mPa·s) at 25° C. of the ink when the ink is prepared, and b represents a viscosity (mPa·s) at 25° C. of the ink after the ink is stored at 70° C. for 1 week.

    摘要: An ink-jet printer is provided. The ink-jet printer includes: an ink container containing an ink, where the ink being a clear ink containing a resin; a discharge head having a nozzle configured to discharge the ink to a printing material; a heater configured to heat the printing material; and a cleaner including a wiper configured to wipe a nozzle formation surface of the discharge head. The ink-jet printer has a matte gloss printing mode imparting a matte gloss and a glossy gloss printing mode imparting a glossy gloss, and the ink-jet printer satisfies a formula below: Tmatte>Tgloss where Tmatte represents a temperature (° C.) of the heater during printing in the matte gloss printing mode; and Tgloss represents the temperature (° C.) of the heater during printing in the glossy gloss printing mode.
