An image forming apparatus having a development unit which develops an electrostatic latent image formed on an image carrier to form a visible image and includes an input unit adapted to accept input of a print job, an analysis unit adapted to analyze the print job, and a prediction unit adapted to predict, based on an analysis result by the analysis unit, a consumption amount of a developing material for printing the print job. In addition, a generation unit generates a schedule for supplying the developing material to the development unit, based on the predicted consumption amount of the developing material, and a supply control unit controls, when a first image data included in the print job has been formed and a second image data included in the print job is formed using the development material having a higher density than a density of the development material needed for forming the first image data, a supply of the development material to the development unit to allow time for stabilizing a density of the development material before image forming of the second image data, based on the schedule generated by the generation unit.
