A liquid droplet discharge apparatus includes: a conveyor which conveys a recording medium in a sub-scanning direction; a head unit including first-kind nozzles and at least one second-kind nozzle; a moving device configured to move the head unit in a main scanning direction intersecting with the sub-scanning direction; and a controller. The controller executes: a first data generation process for generating a first data being used for forming a first image; a second data generation process for generating a second data being used for forming a second image; and a forming process for forming dots by controlling the head unit, the moving device, and the conveyor based on the first data and the second data to discharge liquid droplets on the recording medium.
