    Abstract: In an apparatus to perform printing by ejecting an ink and a printing quality improving liquid for making a coloring agent in the ink insoluble or coagulated, reaction between the printing quality improving liquid and the coloring agent of the ink is certainly caused. Namely, after ejecting the printing quality improving liquid from a head (31), Bk ink, Y ink, M ink and C ink are ejected through heads (30K, 30Y, 30M and 30C) within a given period, e.g. 500 msec. By this, the printing quality improving liquid may react with the coloring agent of the ink before penetrating into a printing medium (106) to certainly make the coloring agent insoluble or coagulated.

    Abstract: When the color printing is performed using a recording head arranged such that the number of nozzles for discharging the black ink is greater than the nozzles for discharging the inks of other colors, the use frequency of some nozzles among all the nozzles for discharging the black ink is higher, so that image unevenness may arise when transferred to the black printing. The present invention provides an ink jet recording method and an ink jet recording apparatus in which the image unevenness often seen in the black printing involving the use of more nozzles than other colors, and the blur of recorded image seen in the image having black image and color image located adjacent are reduced.

    Abstract: An ink jet recording apparatus comprises a carriage (2) movable in a given direction with a recording head (1) which is detachably mountable on it and provided with discharge ports for discharging liquid. The apparatus is arranged to include a sensor (21) for detecting the presence or absence of the carriage, the recording head, and at least one of the ink containers. This sensor is provided for the main body of the apparatus and positioned within the movable range of the carriage. With this arrangement, it is possible to simplify the structure required for detecting whether or not these vital elements for recording are installed without any auxiliary power-supply or memory means.
