Abstract
In an ink jet recording apparatus in which a filter is placed in an ink supply route, when an ink flow is formed in the ink supply route by ink ejection during recording operations and so on, a valve does not contact firmly to the filter, but when an ejection recovery operation is performed and an ink flow velocity increases, the valve contacts firmly to the filter and covers up a part of the filter. With this structure and operation, the effective cross-section area of the filter decreases and hence, a given quantity of pressure difference is produced between the upstream side and the downstream side of the filter. As a result, bubbles unable to pass through the filter at recording operations can pass through the filter when ejection recovery operations are performed.
