    摘要: A representative configuration of an image forming apparatus according to the invention is provided. The image forming apparatus has a plurality of developing devices which develops an electrostatic latent image formed on a photosensitive drum into a toner image using developer of plural colors. The image forming apparatus includes a density sensor which detects the amount of toner of the toner image for each color. In a case where it is determined that the amount of toner of any color departs from a predetermined range based on the detection result of the density sensor, a development condition of the rest developing devices other than the developing device departing from the predetermined range is changed such that the image densities developed by the respective developing devices are equal to each other.
