摘要： An inkjet recording apparatus, includes: a black ink ejecting portion configured to eject a black ink containing a self-dispersion pigment; color ink ejecting portions configured to eject, respectively, a cyan ink, a magenta ink and a yellow ink which contain a polymer emulsion containing 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. When the recording medium is optically transparent and is provided, on a transparent base material thereof, with an ink accepting layer, the recording-controlling unit controls recording on the recording medium such that the color ink ejecting portion is used for recording a monochrome image and a color image which has a plurality of colors, leaving the black ink ejecting portion substantially free from being used.
