Liquid droplet ejecting apparatus and maintenance method

The liquid droplet ejecting apparatus includes a liquid droplet ejecting head, a supply unit, and a control unit. The liquid droplet ejection head ejects liquid droplets of a coloring liquid. The supply unit supplies a coloring liquid to the liquid droplet ejection head. The control unit controls each part. Furthermore, during at least a part of a maintenance period after an ejection period in which the droplets of the coloring liquid are ejected from the droplet ejection head, the control unit controls the supply unit to supply the coloring liquid to the droplet ejection head, the coloring liquid having a lower viscosity than the coloring liquid during the ejection period. 液滴喷出装置具备液滴喷出头、供给部和控制部。液滴喷出头喷出着色液的液滴。供给部向液滴喷出头供给着色液。控制部对各部分进行控制。另外，控制部在从液滴喷出头喷出着色液的液滴的喷出期间之后的维护期间中的至少一部分的期间，控制供给部，向液滴喷出头供给粘度比喷出期间的着色液低的着色液。
