Abstract
The ink jet recording apparatus includes an ejection head for ejecting ink droplets toward a recording medium by exerting electrostatic force onto ink containing charged colorant particles, an ink tank for reserving the ink to be supplied to the ejection head, a circulation path for circulating the ink between the ejection head and the ink tank, and a cleaning mechanism for cleaning the ejection head and the circulation path using cleaning liquid. The cleaning liquid circulated through the circulation path at a time of cleaning by the cleaning mechanism is obtained by adding a charge control agent to an ink dispersion medium.
