Abstract
A recording apparatus is provided with a droplet discharging head having a nozzle forming portion and a charging unit. The nozzle forming portion includes nozzles formed therein. The charging unit is configured to impart an electrical charge to the medium. The charging unit imparts, to the medium, an electrical charge having the same polarity as an electrically charged state of the nozzle forming portion after the droplets are discharged.
Claims9
A recording apparatus comprising:
- a droplet discharging head configured to discharges droplets onto a medium from a nozzle forming portion including nozzles, the nozzles being formed in the nozzle forming portion, the droplets having a first polarity and the nozzle forming portion having a second polarity that is opposite of the first polarity;
- and
- a charging unit configured to provide an electrical charge to the medium, the provided electrical charge being generated by the charging unit,
- wherein the charging unit provides, to the medium, a specific amount of an electrical charge having the second polarity,
- wherein the specific amount of the electrical charge provided by the charging unit to the medium is determined by one of:
- for each specific time that the droplets are discharged, a discharge rate of the droplets discharged onto the medium during the specific time, or
- a maximum discharge rate of the droplets discharged onto the medium.
