Abstract
An image forming apparatus of an ink-jet type of the present invention is provided with an ink head section having a carriage that is composed of a plurality of ink head and scans so as to print. The ink head section is provided with black ink heads and a color ink head in such a manner that the black ink heads sandwich the color ink head. This eliminates the difference in blackness in printing, even if the carriage scans in two ways so as to print. Meanwhile, the ink heads are increased in number only by one, thereby limiting an increase in cost. In short, without a large increase in cost, it is possible to provide an image forming apparatus that forms a high-quality image, while printing time is shorted since the printing is carried out in two ways in a scanning direction.
