An object of the present invention is to reduce the amount of solvent vapor floating around when a print head is cleaned in an inkjet recording device. In addition, an object is to reduce ink stains on a periphery of the print head. An inkjet recording device includes a main body portion and a print head. The main body portion includes an ink container that contains ink, and a solvent container that contains a solvent. The print head includes a nozzle connected to the ink container to discharge the pressurized and supplied ink, a charging electrode that charges ink particles discharged from the nozzle, a deflection electrode that deflects the ink particles charged by the charging electrode, and a gutter that collects the ink. In addition, a head mounting unit for cleaning the print head is provided. The head mounting unit is connected to a solvent vapor suction path for suctioning solvent vapor generated therearound.
