Abstract
An ink jet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, and a controller. The recording head includes an ink ejection surface having an ink ejection port from which ink is ejected. The cleaning liquid supply device includes a cleaning liquid supply surface having a cleaning liquid supply port from which cleaning liquid for wiping the ink ejection surface with the wiper member is supplied, and is located upstream of the ink ejection surface in a wiping direction. The controller controls a cleaning operation including squeezing out the cleaning liquid containing bubbles from the cleaning liquid supply port, and moving the wiper member carrying the cleaning liquid containing bubbles, in the wiping direction from a movement start position to an end position ahead of the ink ejection surface.
