Abstract

In an image forming apparatus, a liquid ejection head has at least one ejection hole, and a conveyor moves a recording medium relative to the ejection head. A deflector deflects liquid droplets ejected from the ejection hole in a direction including at least a component of a direction substantially parallel to relative conveyance direction of the recording medium. A deflection angle setter sets two or more deflection angles such that when dots mutually adjacent in the direction substantially parallel to the relative conveyance direction of the medium are formed in an overlapping fashion, directions of flight of droplets ejected consecutively are deflected such that their directions of flight become different from each other. Droplet landing time differential between the first droplet and the second droplet becomes equal to or greater than quasi-fixing time period from a landing time of the first liquid droplet until the first liquid droplet becomes quasi-fixed.
