ABSTRACT:
In printing with black ink ejected through ejection openings of a corresponding ejection opening array of a printing head for reacting with other color inks ejected through ejection openings of color ejection opening arrays, during wiping, the respective ejection opening arrays or the group of ejection opening arrays and the vicinities thereof are wiped using two blades corresponding to the black and other color ejection opening arrays, respectively, and each forming a predetermined angle with respect to a direction orthogonal to a wiping direction. Thus, the wiped-away ink or the like is collected in a portion between the black ejection opening array and the color ejection opening arrays so as to be away from the corresponding ejection opening arrays, and is then wiped by another blade.
