Abstract
An inkjet printing apparatus includes an ink tank, a print head, an ink flow passage, a degassing device, a circulation flow passage and a circulation pump. The print head discharges ink supplied from the ink tank through the ink flow passage. The degassing device is disposed midway in the ink flow passage and removes air from the ink. The circulation flow passage has two ends respectively connected to two sides of the degassing device. The circulation pump is disposed midway in the circulation flow passage and returns the ink flowing out of the degassing device to a position to flow in the degassing device. The ink flow passage between an outflow port from the circulation flow passage and an inflow port thereto and the circulation flow passage are formed such that the ink is movable at approximately a constant speed.
