Abstract
A liquid ejection inspecting apparatus includes: (A) a sensing section; (B) a detection section; and (C) a determination section. The sensing section is arranged in a state of non-contact with a liquid ejection nozzle for ejecting a liquid. The sensing section has a sensing surface arranged in a direction in which the liquid is ejected from the liquid ejection nozzle. The detection section is for detecting an induced current generated in the sensing section due to the liquid which has been ejected from the liquid ejection nozzle and charged electrically. The determination section is for determining whether or not ejection of the liquid from the liquid ejection nozzle is being normally performed, based on the induced current detected by the detection section.
