An image forming apparatus includes: a recording head having plural sub-heads, the sub-heads each including plural nozzles, each of the plural nozzles within a sub-head ejecting liquid droplets at the same time with respect to a medium on which an image is drawn, and the sub-heads being arranged in a width direction of the medium; a setting unit; and a rotation unit. The setting unit uses a timing when a predetermined sub-head of the plural sub-heads ejects liquid droplets as a reference to set timings when sub-heads other than the predetermined sub-head eject liquid droplets. The rotation unit uses a predetermined axis as a spindle to rotate and position the recording head in a plane parallel to a plane of the medium.
