Abstract
A cleaning member includes an elastic blade member that elastically deforms when its rounded tip end portion wipes an ejection orifice surface of an ink jet recording head. The rounded portion has a curved surface with a predetermined curvature with respect to the direction of relative movement of the elastic member and the recording head. Thus, a substantially fixed contact angle can be maintained between the rounded portion and the ejection orifice surface during wiping. The cleaning member moves between a cleaning position for cleaning the ejection orifice surface of the recording head and a non-cleaning position spaced from the recording head.
