Claim:
An inkjet recording apparatus, comprising: a black ink ejecting portion configured to eject a black ink containing a self-dispersion pigment, and a polymer emulsion as a fixing agent; color ink ejecting portions configured to eject, respectively, a cyan ink, a magenta ink and a yellow ink which comprise a polymer emulsion which comprises a polymer fine particle containing a coloring material which is insoluble in water or slightly soluble in water; and a recording-controlling unit configured to control recording, wherein the black ink ejecting portion and the color ink ejecting portion scan relative to a recording medium, to thereby record an image on the recording medium, wherein when a black color area in the color image is recorded in the following cases: i) the recording medium is optically transparent and is provided, on a transparent base material thereof, with an ink accepting layer, and ii) the recording medium is provided, on an opaque base material thereof, with an ink accepting layer which has a surface having a gloss, the recording-controlling unit controls recording such that the black color area in the color image is recorded by all of the cyan ink, the magenta ink and the yellow ink in combination without black ink, and wherein when a black color area in the color image is recorded in the following cases: iii) a color image is recorded on a plain paper sheet, and iv) the recording medium for recording the color image is provided, on an opaque base material thereof, with an ink accepting layer which has a surface free from a gloss, the recording-controlling unit controls recording such that the black color area in the color image is recorded by all of the black ink, the cyan ink, the magenta ink and the yellow ink in combination.
