Abstract
There are provided a printing apparatus and printing method capable of achieving high-quality printing by fine ink droplets, and collecting unwanted ink droplets. According to the method, ink droplets discharged from a printhead are negatively charged by the negative ions in printing. A printing medium is charged positively opposite to the polarity of ink droplets. By the electrostatic force, discharged ink droplets travel toward the printing medium, and the amount of ink droplets attached to the printing medium is increased. In addition, an ink mist collecting unit having a positive electrode is employed to collect floating ink mist.
