A gray-scale display device such as a general display for a personal computer or work station, a laser printer or a color printer. A gray-scale font generating apparatus used in the display device includes an input unit for inputting the information representative of a font code, and control unit for acquiring a blend ratio in accordance with the ratio of a font area and a background area in the contour of the shape data of the font corresponding to the information representative of a font code, and making the gradation display of the font with the blend ratio thus acquired. Since the blend ratio is acquired without using work memory, a gray-scale font can be created and outputted at high speed.
