Image forming apparatus, information processing device, and image forming methdo

An information processing device to create print data for an image forming apparatus including a carriage carrying an image forming unit that has at least two nozzle lines each having multiple nozzles to discharge different color droplets, the carriage reciprocating in a direction crossing an arrangement direction of the nozzles and create the pint data for dual directional printing in which an image is formed in an outward and a return of the carriage to discharge droplets of each color by using, of each of the nozzles in the at least two nozzle lines, the nozzles located at different positions in the arrangement direction of the nozzles while not overlapping in the direction of movement of the carriage.

An image forming method comprising:

• dual-directionally printing an image in an outward and a return of a carriage that carries an image forming unit having at least two nozzle lines each having multiple nozzles to discharge different color droplets and reciprocates in a moving direction crossing an arrangement direction of the nozzles,
• wherein in the dual-directional printing, of each of the nozzles in the at least two nozzle lines, the different color droplets are discharged by using the nozzles located at different positions in the arrangement direction of the nozzles while not overlapping in the moving direction of the carriage.
