ABSTRACT:
An image recording apparatus includes liquid ejection heads, wipers, and a movement means. The liquid ejection heads respectively have ejection faces, and are arranged in such a manner that the ejection faces form two rows extending in one direction and in addition two of the ejection faces included in different rows do not overlap each other along a direction perpendicular to the one direction. The liquid ejection heads are divided into one or more head groups each including two of the liquid ejection heads corresponding to the different rows. The movement means moves two of the wipers associated with two liquid ejection heads belonging to each head group, from inner end portions of the ejection faces in opposite directions along the perpendicular direction while keeping the two wipers in contact with the ejection faces.
