In a printer in which an inkjet head is mounted in a carriage, which is movable in a direction intersecting with a conveyance direction of a recording medium, and ink is ejected from the inkjet head to record an image onto the recording medium, there has been a problem in that the recording medium is charged due to friction and separation at the time of conveyance of the recording medium, and ink mist is attracted to a portion charged to have an unexpected pattern to be recorded. In view of this problem, static electricity generated on the recording medium is removed by providing the 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 scanning of the carriage. The static electricity can be removed efficiently by arranging on the carriage the ionizers for generating the ions of both polarities, namely, the positive ions and the negative ions. |

1. An inkjet printer for conveying a recording medium intermittently, ejecting ink from a recording head, and recording an image onto the recording medium, the inkjet printer comprising:
the recording head for ejecting the ink to the recording medium from a plurality of nozzles; conveyance means for conveying the recording medium; a carriage having the recording head mounted therein, the carriage being reciprocable in a direction intersecting with a conveyance direction of the recording medium; a platen arranged so as to be opposed to a surface of the recording head on which the plurality of nozzles are arranged, for holding the recording medium being conveyed by the conveyance means; a housing having at least the platen and the carriage accommodated therein; a first ionizer for generating a positive ion; a second ionizer for generating a negative ion; a first drive circuit for driving the first ionizer; a second drive circuit for driving the second ionizer; and control means for controlling the first drive circuit and the second drive circuit, wherein the first drive circuit and the second drive circuit are controlled by the control means independently of each other. |
