Claim:
1. A liquid ejector comprising: 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 comprising: a droplet landing surface arranged opposed to the nozzle surface, on which the droplet ejected from the plurality of nozzles of the head lands; 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 by relatively moving the wiper and the contact surface in the first direction while the wiper deforms elastically by contact and pressed against the contact surface of the cleaner after the wiper wipes the droplet landing surface, wherein: the contact surface having a curvature such that side ends of the wiper, arranged in a second direction perpendicular to the first direction, contacts with the contact surface at first, and then a center part of the wiper contacts the contact surface.
