In an inkjet printer, there has been a problem in that a recording medium is charged with electricity due to friction and separation at the time of conveyance of the recording medium, and ink mist is attracted to a portion charged with electricity to have an unexpected pattern to be recorded. In view of this problem, static electricity generated on the recording medium is removed by providing a carriage with an ionizer for generating a positive ion and an ionizer for generating a negative ion and generating the ions at the time of scan of the carriage. Through the arrangement of the ionizers for generating the ions of both polarities, namely, the positive ion and the negative ion, on the carriage, and on/off control on the ions to be generated in each scan, an amount of ions to be supplied per unit area of the recording medium can be made uniform, with the result that the static electricity can be removed efficiently. |
