Abstract
An ink jet printing apparatus includes a mechanism for cleaning the face of an ink jet head by wiping the face with a wiper to which a liquid for the head is transferred. The face of the ink jet head is provided with ejection openings from which inks containing coloring materials are ejected. The apparatus also includes an absorber for holding the liquid, the absorber being disposed below an area where the liquid for the head is going to be transferred to the wiper in the direction of gravity, and a transferring member which includes a section connected to the absorber to receive the liquid and a section which abuts on the wiper to perform the transfer. The transferring member is configured to move the liquid for the head by a capillary force from the section which receives the liquid to the section which performs the transfer.
