ABSTRACT:
Ejection inspection of nozzles for a liquid such as ink is enabled to be carried out easily. A method for inspecting liquid ejection includes: a step of ejecting an electrically-charged liquid from a nozzle subjected to ejection inspection; and a step of determining that the liquid has been ejected if an induced current is produced by the liquid ejected from the nozzle in a sensing section provided in a state of non-contact to the nozzle, and determining that the liquid has not been ejected if the induced current is not produced in the sensing section.
