Abstract
A circulating type ink supply system includes an upstream ink tank, an upstream ink flow channel connected at one end thereof to the upstream ink tank, a nozzle branch portion connected to the other end of the upstream ink flow channel and being in communication with a nozzle configured to discharge ink, a downstream ink flow channel connected at one end thereof to the nozzle branch portion and a downstream ink tank connected to the other end of the downstream ink flow channel, wherein an energy per unit volume determined by a sum value of a static pressure and a potential energy of the ink in the upstream ink tank when the circulation of the ink is stopped does not exceed the energy per unit volume of the ink at an atmospheric pressure at a level of the nozzle.
