This invention provides an image forming apparatus, which attains a uniform gloss level of an overall image by preventing regions having different gloss levels from being generated on the image to be formed upon execution of image formation using a transparent toner, and a control method thereof. To accomplish this, an image forming apparatus of this invention identifies pixels to be developed using only a black toner of colored toners from an image signal of an image to be formed on a printing material upon execution of image formation using the transparent toner. Furthermore, the image forming apparatus executes exposure control so as to perform development using the transparent toner in an amount required to reduce a gloss level difference between the pixels to be developed using only the black toner and those to be developed using the colored toners other than the black toner.
