An image forming apparatus includes a control unit with a reduction mode using a reduced consumption of the color material. The reduction rule includes a rule of conversion configured to, in a constant hue plane of the input color value, move all color values on a straight line passing through a lowest brightness color value and the input color value in a direction from a highest saturation color value to a highest brightness color value, so as to convert into color values on a straight line passing through the lowest brightness color value and a converted input color value where the input color value is converted, the lowest brightness color value being indicative of a color value of lowest brightness, the highest saturation color value being indicative of a color value of highest saturation, the highest brightness color value being indicative of a color value of highest brightness. |
