Abstract
An ink jet recording apparatus is provided with a black head and a plurality of color heads. The black head has a predetermined number of first orifices aligned at predetermined intervals (e.g. 0.0169 mm) in a sub scanning direction (direction in which a print medium travels). The plurality of color heads eject different colored ink drops. Each color head has the predetermined number of second orifices aligned in the sub scanning direction perpendicular to the main scanning direction. The second orifices of adjacent color heads are aligned in a main scanning direction perpendicular to the sub scanning direction.
