Abstract
A cap for capping the single surface of a recording head that is formed with a plurality of groups of ejection holes for inks of different colors so as to maintain an ink-ejectable condition of the recording head has an interior divided into a plurality of spaces individually corresponding to the plurality of ejection hole groups for different-color inks. The spaces include at least a first space corresponding to the ejection hole group for a black ink, and a second space corresponding to the ejection hole groups for yellow, magenta and cyan inks. The plurality of spaces are integrated in a single cap. When an ink-jet recording apparatus includes such a cap, a condition for proper ejection of ink is maintained in the apparatus and requires only a small system.
