Abstract: An image forming method: imaging an image forming medium in the image forming unit to generate medium image data representing the image forming medium; controlling an image formation in a plurality of modes including a single-side image forming mode and a duplex image forming mode; and detecting an ink stain based on tone differences between first medium image data and second medium image data by comparing the first medium image data as medium image data representing one surface of the image forming medium and the second medium image data as medium image data representing another surface of the image forming medium when the duplex image forming mode is selected. The controlling includes setting the whole image formable region as the target of the ejection restriction process in response to the detection of the ink stain to inhibit an ejection of the ink to the other surface.
