An image forming apparatus provides enhancement of image quality. The image forming apparatus includes a window generating unit to generate a main window of a predetermined size using a Lines Per Inch (LPI) and an angle of a dithering mask, and to generate a plurality of subwindows within the generated main window, a determining unit to determine the presence of an edge area by applying the plurality of generated subwindows to a binary image and according to pixel values of the binary image that correspond to the subwindows, and a control unit to determine a dot size of a central reference pixel at the center of the main window, according to the presence and absence of the edge area. Because image quality is enhanced adaptively according to edge and smooth areas, print quality improves.
