Abstract
A wiper device includes a wiper member, a wiper cleaner, and an ink absorbing material. The wiper member wipes a nozzle opening surface of a recording head of a printer. The wiper cleaner always contacts the portion of the wiper member other than the distal end of the wiper member. The wiper cleaner scrapes off the ink adhered to the wiper member and absorbs the ink. The wiper cleaner guides the absorbed ink to the ink absorbing material. The ink absorbing material has an ink absorbability higher than that of an absorption body of the wiper cleaner. The wiper cleaner is thus prevented from becoming saturated with the ink.
