Claim:
An inkjet recording apparatus comprising: an inkjet head that ejects ink on a printing medium; a conveyance motor causing conveyance of the printing medium; a discharge motor causing discharge of the printing medium; a printing medium surface sensor, located at an upper-stream side of the inkjet head apart from the inkjet head in a printing medium conveyance direction, that senses a foreign substance representing an image printed on the printing medium beforehand; and a controller that 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.
