The transfer inkjet printer device includes an intermediate transfer body including an intermediate transfer surface capable of moving along a rotation route; an inkjet head used to discharge ink including toner particles onto the intermediate transfer surface at a first area in the rotation route in a state where the toner particles are charged, so as to form an intermediate image composed of an ink layer on the intermediate transfer surface; a pressure device used to press the ink layer of the intermediate image on the intermediate transfer surface, onto a surface of a recording medium at a second area in the rotation route; and an electric field application device used to electrophorese the charged toner particles in the ink layer of the intermediate image toward the recording medium at the second area.
