Abstract
An object of the present invention is to appropriately dispense treatment fluid to wipers, and to always wipe ejection-orifice formation surfaces in a favorable state regardless of an environmental change and the like. To this end, in the present invention, a treatment-fluid holding portion holds treatment fluid used in a wiping operation of wipers. When the wipers contact the treatment-fluid holding portion, the treatment fluid is transferred to the wipers. In an environment where the treatment fluid is thickened, the wipers with ink dispensed thereto are brought into contact with the treatment-fluid holding portion to supply ink to the treatment-fluid holding portion. Thus, the viscosity of the treatment fluid near a contact portion between the treatment-fluid holding portion and the wipers decreases, and the treatment fluid is sufficiently transferred to the wipers.
