摘要： In general, according to one embodiment, an inkjet recording apparatus includes an inkjet head, a conveyance motor, a discharge motor, a printing medium surface sensor and a controller. The inkjet head ejects ink on a printing medium. The conveyance motor causes conveyance of the printing medium. The discharge motor causes discharge of the printing medium. The printing medium surface sensor, locates at the upper-stream side of the inkjet head apart from the inkjet head in a printing medium conveyance direction, senses a foreign substance representing an image printed on the printing medium beforehand. The controller drives the discharge motor to discharge a printing medium without ejecting ink from the inkjet head if an after-printing mode in which printing is made on the printing medium on which the image is printed beforehand is not set if the foreign substance is detected on the printing medium through the printing medium surface sensor, or drives the discharge motor to discharge a printing medium after ejecting ink on the printing medium from the inkjet head if the after-printing mode is set if the foreign substance is detected on the printing medium through the printing medium surface sensor.
