Abstract: This invention relates to an ink jet recording apparatus and a recording method for recording images of high density with the amount of ink placed per unit area on a recording medium being kept constant even if the resolvability when recording is changed. When the amount of ink of an ink droplet discharged from a recording head is constant (25 pl), the average number of recorded dots conforming to the resolvability is found on the basis thereof, and the number of recordable dots is found from this average number of dots. The difference between this number of actually recorded dots and the average number of recorded dots is adjusted by reducing the value of recording data in advance.

Abstract: A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.
The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.

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.

Abstract: According to the present invention, there is provided an ink jet recording apparatus for recording an image on a recording medium by discharging ink to the surface of the recording medium, wherein ink is reserved in an ink tank including a negative pressure generating member, such as an absorber and a foaming member, and a function of accurately detecting the residual quantity such that depletion to a predetermined level can be detected is realized. Light emitted by a photointerrupter is allowed to pass through a portion of a wall surface of the ink tank made of transparent plastic or the like which is transmissible with respect to detection light emitted by the photointerrupter to detect change in the light reflectance in the boundary portion between the wall surface and the ink absorber. In accordance with reflectance obtained in a case where no ink exists in the detected portion and that obtained in a case where ink exists, the residual quantity of ink can be detected.
