The image forming apparatus comprises: a long liquid droplet ejection head in which a plurality of nozzles are arranged; a conveyance device which attracts a recording medium by means of electrostatic attraction and conveys the recording medium in a sub-scanning direction substantially perpendicular to a main scanning direction; a dividing device which divides a print region into a plurality of blocks, the blocks including a first blocks and a second blocks situated next to the first blocks in the sub-scanning direction; and a control device which drives, at a substantially simultaneous drive timing, a plurality of mutually adjacent nozzles corresponding to the plurality of blocks, wherein a boundary line that divides the print region in the first blocks in the main scanning direction and a boundary line that divides the print region in the second blocks in the main scanning direction are discontinuous from each other in the sub-scanning direction.
