Abstract
An ink jet recording apparatus includes an ejection head which ejects an aqueous ink composition containing a resin component, a water-soluble organic solvent having a boiling point of 250° C. or less, a surfactant, and water; a first cap device which covers and moisturizes the ejection head; and a first maintenance liquid supply device which supplies a maintenance liquid to the first cap device. The maintenance liquid contains water and at least one water-soluble organic solvent of alkanediols having a boiling point of 250° C. or less and alkylene glycol monoether derivatives having a boiling point of 250° C. or less.
Claims14
An ink jet recording system, comprising:
- an aqueous ink composition comprising a resin component, a water-soluble organic solvent having a boiling point of 250° C. or less and including at least one pyrrolidone derivative, a surfactant, and water, the aqueous ink composition not including a water-soluble organic solvent having a boiling point above 250° C.;
- a maintenance liquid comprising water, and a water-soluble organic solvent of at least one of alkanediols having a boiling point of 250° C. or less and alkylene glycol monoether derivatives having a boiling point of 250° C. or less, the maintenance liquid not including a water-soluble organic solvent having a boiling point above 250° C.;
- and
- an ink jet recording apparatus comprising:
- an ejection head configured to eject the aqueous ink composition,
- a first cap device configured to cover and moisturize the ejection head and form a substantially closed space at the ejection head, and
- a first maintenance supply device configured to supply the maintenance liquid to the first cap device, the supplied maintenance liquid being evaporated to humidify the substantially closed space.
