CLEANING APPARATUS AND LIQUID EJECTION APPARATUS AND CLEANING METHOD
The cleaning apparatus cleans a nozzle surface of a liquid ejection head. The cleaning apparatus includes: a cleaning liquid supply device which supplies cleaning liquid to the nozzle surface while being not in contact with the nozzle surface; a liquid layer formation control device which causes the cleaning liquid supply device to supply a prescribed amount of the cleaning liquid to form a layer of the cleaning liquid that fills in a space between the cleaning liquid supply device and the nozzle surface; and a movement control device which controls a movement device so as to move the cleaning liquid supply device and the liquid ejection head relatively to each other at a relative speed in which a meniscus is not broken down, the meniscus being of the layer of the cleaning liquid in a portion of the layer of the cleaning liquid that makes contact with the nozzle surface.
