Abstract
The internal space of a storing container is separated by a flexible membrane into a first storing space storing an ejection material and a second storing space storing an operating liquid. A change in electrical property of the flexible membrane resulting from entry of at least one of the ejection material and the operating liquid to the inside of the flexible membrane is detected.
