Abstract
A liquid ejector includes a head having a plurality of nozzles arranged along a first direction of a nozzle surface of the head to eject a droplet from the nozzles, and an ejection detector to detect whether or not a droplet is ejected from the plurality of nozzles of the head by detecting an electrical change generated when the droplet lands onto the ejection detector. The ejection detector includes a droplet landing surface arranged opposed to the nozzle surface, a wiper to wipe the droplet off the droplet landing surface along the first direction, and a cleaner having a contact surface to remove the droplet adhered to the wiper after the wiper wipes the droplet landing surface. The contact surface has a curvature such that side ends of the wiper contacts with the contact surface at first, and then a center part of the wiper contacts the contact surface.
