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.
  In the foregoing embodiments, ink is described as being liquid. Another ink which may be used in the present invention is an ink which solidifies at or below room temperature and softens at room temperature, or an ink which remains a liquid, or an ink which is in a liquid state when a recording signal is applied since, in general, in carrying out the above-described ink-jet recording method, an ink itself is adjusted to a temperature range from 30 the ink falls within a stable ejection range thereof.
