Abstract
An apparatus for ejecting liquids includes a liquid ejection head including a nozzle, the nozzle ejecting the liquids; and an ejection detector to detect whether the liquids are ejected from the nozzle of the liquid ejection head, the ejection detector including an insulated receiver having an adhering face to receive and adhere the liquids ejected from the nozzle and an electrode disposed on an opposite side of the adhering face of the receiver. The ejection detector detects electrical change generated when the liquids adhere to the adhering face of the receiver while generating a potential difference between the liquid ejection head and the electrode.
