Kind Code:
A1
Abstract:
A cleaning liquid, usable for cleaning of an ink-jet recording apparatus, includes: a nonionic surfactant, solubility of the nonionic surfactant in water at 20°C being less than 0.2% by mass; a first water-soluble organic solvent of which solubility parameter is not less than 13; a second water-soluble organic solvent of which solubility parameter is less than 12; and water. The cleaning liquid satisfies the following conditions (1) to (4): Condition (1): X ≥ 0.1; Condition (2): A - B ≥ 0; Condition (3): B / X ≥ 15; Condition (4): 10 ≤ A + B ≤ 60. X: a content amount (% by mass) of the nonionic surfactant, A: a content amount (% by mass) of the first water-soluble organic solvent, and B: a content amount (% by mass) of the second water-soluble organic solvent.
