Claim Text:
1. An image producing apparatus comprising: a recording head for ejecting ink droplets of inks that are curable upon exposure to ultraviolet light or active light rays to form dots in a plurality of colors having different shades on a recording medium; a head drive circuit for controlling the recording head based on a control signal to successively form the dots at a plurality of timings on the recording medium, to thereby generate image arrays in a transverse direction across the recording medium while the recording medium is moved in a feed direction with respect to the recording head; an image processor for generating the control signal, which is supplied to the head drive circuit, from an input image signal, so that if the dots formed along the transverse direction are classified into plural groups depending on the plurality of timings, then preceding dots, which belong to a group having an earliest timing, are formed in a pale color; and curing light sources for applying the ultraviolet light or the active light rays to the ink droplets, which are deposited on the recording medium, wherein after ink droplets of the preceding dots are deposited on the recording medium and before ink droplets of subsequent dots are ejected from the recording head, the curing light source applies the ultraviolet light or the active light rays to the droplets of the preceding dots deposited on the recording medium.
