1. A method of printing a mono-color image using a single-pass color printer, which includes a plurality of photosensitive substances, on which a plurality of toner images of different colors are formed, an intermediate transfer belt for rotating while contacting the plurality of photosensitive substances, a plurality of transfer units facing the plurality of photosensitive substances to provide a rear surface of the intermediate transfer belt with an electric field, and a plurality of blades for contacting the plurality of photosensitive substances to remove toner remaining on the photosensitive substances after performing a transfer process, the method comprising: developing dummy toner images onto the photosensitive substances that do not perform an image forming operation to correspond to a non-image region of the intermediate transfer belt, to which a toner image transferred from the photosensitive substance performing the image forming operation is not attached, in order to reduce a friction between the blade and the photosensitive substances that are not related to the image forming operation, if a mono-color image is printed.
