Abstract
An ink jet ejection head suitable for realizing maintenance of an ink jet head in such a manner as restoring ink ejection performance and ensuring satisfactory application free from an ejection failure in one or more nozzles. The ink jet ejection head of a liquid material application apparatus has an ink jet head, a head holding member for holding the ink jet head in a detachable manner, and a changing-over mechanism connected to a liquid supply passage and a pressurized air supply passage. The changing-over mechanism selectively supplies one of a liquid and pressurized air to the ink jet head. The liquid material application apparatus includes the ink jet ejection head.
