Abstract
An image forming method includes discharging a droplet of a recording fluid via nozzles of a recording head onto a print medium; performing a main scan in which the print medium is scanned in a main scan direction; performing a sub-scan in which the print medium is scanned in a sub-scan direction; determining an overlap region in an image region that is formed by a single main scan; and performing an overlap control by forming an image in the overlap region through a plurality of main scans while the print medium is moved in the sub-scan direction by a feed amount L, wherein L=(n−x)d−md, where n is a number of the nozzles in the recording head; x is a number of the nozzles in the overlap region; d is a nozzle pitch; and m is a feed correcting coefficient (0<m<1).
