Patent ID: 8449063

Claim:
A liquid ejecting apparatus comprising: an ejected medium transportation unit that transports an ejected medium; a liquid ejecting unit that ejects liquid onto the ejected medium while moving in a second direction which is perpendicular to a first direction as a transportation direction of the ejected medium; an ejected medium supporting unit that is arranged so as to be opposed to the liquid ejecting unit and supports the ejected medium; and wherein the liquid ejecting apparatus alternately executes transportation of the ejected medium by the ejected medium transportation unit and liquid ejection by the liquid ejecting unit so as to complete liquid ejection onto the ejected medium, wherein, in the liquid ejecting apparatus, a potential controller is provided that is capable of switching states between a same potential state where potentials at a predetermined portion at the side of the liquid ejecting unit and a predetermined portion at the side of the ejected medium supporting unit are the same and a potential difference generation state where a potential difference is generated between the predetermined portion at the side of the liquid ejecting unit and the predetermined portion at the side of the ejected medium supporting unit, the potential controller forms the same potential state while the ejected medium is transported by the ejected medium transportation unit, and the potential controller forms the potential difference generation state in at least an appropriate period while the ejected medium is not transported by the ejected medium transportation unit.
