<P>PROBLEM TO BE SOLVED: To reduce a bi-directional color difference with a simple configuration. <P>SOLUTION: A black head 4k2 is disposed to have a displacement equal to one nozzle row width in the sub-scanning direction downstream in a medium conveying direction with respect to a color nozzle head 4c1 and a second color head 4c2. After an image is formed by the first color head 4c1 and the second color head 4c2 in main scanning in one direction, a paper sheet 10 is distributed for one line. The second black head 4k2, in main scanning in another direction, forms an image by ejecting a black liquid on the image that is formed in the main scanning in the one direction, by the first color head 4c1 and second color head 4c2 to complete the image. <P>COPYRIGHT: (C)2013,JPO&INPIT |
