摘要： A liquid droplet jetting apparatus includes a jetting unit equipped with plural head modules, a supply channel equipped with plural branching channels, first circulation limiting units, liquid storage units and external force applying units. The first circulating limiting units allow circulation of a liquid in a direction from a storage chamber to each of the head modules and limit circulation of the liquid in an opposite direction of the circulating direction. The liquid storage units are disposed between the circulation limiting units and the head modules. The liquid storage units store the liquid, and the volumes of the liquid storage units change due to external force. The external force applying units apply the external force to the liquid storage units such that the volumes of the liquid storage units become smaller and cause liquid droplets to be jetted from the nozzles.
