An ink-jet type printing apparatus includes a recording medium conveyor device, an ink-jet head for forming an image on a conveyed medium, and a bubble extracting device. The ink-jet head has an ink storing chamber, orifices located under the chamber and extending downward from the chamber, ink ejection driving elements for ejecting ink from the orifices, and a bubble extracting path located aside from the orifices and extending downward from an upper part of the chamber. The extracting device extracts bubbles from the upper part of the chamber through the path while the orifices do not ejecting ink for forming the image.
