    摘要： This specification discloses an ink jet recording apparatus in which the density of black can be emphasized as compared with that of the other colors, with time cost, hue and blur in the boundary between different colors being suppressed, and wherein when ink is impacted from a multihead to all picture elements in a predetermined area, discharge by a plurality of multinozzles is effected to an image datum at the same position and in the same scan with an amount of ink per discharge for which the area factor in the area is less than 100% and the amount of ink per discharge from a multihead for one color is made greater than that for the other colors.

    摘要： An ink jet recording apparatus for recording information by ejecting ink fluid on a recording medium includes a recording head, a cap, an ejection restoration mechanism, an atmospheric air opening mechanism and a heating mechanism. The recording head has an orifice and ejects ink fluid from the orifice. The cap covers up a face on which the orifice of the recording head is disposed. The ejection restoration mechanism performs procedures for keeping a state of ejection of ink fluid by the recording head to be good by discharging ink fluid into the cap. The atmospheric air opening mechanism makes an inside of the cap opened to an atmospheric air when the restoration operations are being performed by the ejection restoration mechanism. The heating mechanism heats the recording head at least before the restoration operation is performed by the ejection restoration mechanism.
