Abstract
An ink jet apparatus where a filter is provided in an ink inflow channel connecting an ink tank with the inside of an ink jet head to discharge ink from nozzles, and in an ink outflow channel connecting the inside of the ink jet head with the ink inflow channel. The ink passes through the inside of the ink jet head, and bubbles existing inside the ink jet head move with the ink to the outside. Further, as foreign materials are repeatedly removed from the ink, bubbles in the ink jet head can be removed with a simple construction and the occurrence of ink discharge failure can be reliably suppressed.
