/Ink-jet Recording Apparatus
Abstract

An inkjet recording apparatus 1 includes: a deaerator 30 for deaerating ink I flowing in a second flow passage 92; and a circulation pump 62 for applying pressure to a circulation path of the ink I including a sub-tank 52, the second flow passage 92, the deaerator 30, a third flow passage 93, a head 11, and a fourth flow passage 94, to generate an ink flow of the ink I in the circulation path. The deaerator 30 has an ink inlet 12A and an ink outlet 12B, and the ink inlet 12A is arranged at a position closer to the head 11 than the ink outlet 12B in a direction in which the ink I is ejected from a nozzle row 16.
