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.
