Abstract
An ink circulation system includes: an ink-jet head in which a shared ink flowing route is formed, an ink tank, a supply flowing route for supplying ink from the ink tank to the shared ink flowing route, a reflux flowing route for refluxing the ink from the shared ink flowing route to the ink tank, and a differential pressure generating unit for generating a differential pressure in the ink tank. The differential pressure generating unit is equipped with an impeller placed inside the ink tank, and a drive unit placed outside the ink tank. Then, the drive unit operates to turn the impeller, by means of remote driving, for generating a differential pressure between a supply port of the supply flowing route and a reflux port of the reflux flowing route so as to circulate the ink through the ink flowing route.
