Abstract
An ink-jet recording apparatus ejects droplets of a recording-improvement liquid on a boundary line between two different color portions of an image by using an ink-jet recording head. The ink-jet recording head comprises a group of nozzles for ejecting the recording-improvement liquid which is responsible for precipitating or condensing a coloring substance in the ink. Accordingly, a high-quality image that comprises black-color portion with a high image density without causing any feathering and multiple-color portions without a spread of ink can be obtained.
