Abstract: An inkjet printing apparatus includes a conveyer conveying a printing medium; an image former discharging ink on the printing medium; a mover relatively moving the image former and the conveyer; a first detector; a second detector; and a controller controlling image formation. The mover performs a first move operation to expand a distance between the image former and the printing medium and a second move operation to expose the conveying surface. Upon detection of an abnormal conveyance state of the printing medium by the first detector, the conveyer stops conveyance and the mover performs the first move operation. After stopping the conveyance and the first move operation, the controller checks for the contact of the printing medium and the image former during the second move operation based on the detection results at the second detector, and only if no contact is determined, the mover performs the second move operation.
