A liquid droplet ejection device includes a recording section, a moving section, and a driving signal supplying section. In the recording section, plural liquid droplet ejectors are arrayed, each liquid droplet ejector has a driving element, and ejects a liquid droplet onto a recording medium in response to a driving signal being supplied to the driving element. The moving section moves the recording section and the recording medium relative to one another in a direction intersecting the array direction of the liquid droplet ejectors. The driving signal supplying section generates, when plural types of liquid droplets having different droplet volumes are ejected onto the recording medium while the recording section and the recording medium are moved relatively, the driving signals such that, the smaller a droplet volume of a liquid droplet, the faster the ejection speed of the liquid droplet.
