An image forming apparatus image forming means for forming a toner image using light color toner and dark color toner which have the same hues and which have different densities; detecting means for detecting a density of a toner image for reference which is formed by the image forming means, the reference toner image including a number of portions corresponding to different image density levels; control means for controlling an image forming condition of the image forming means in accordance with an output of the detecting means, wherein a difference between the image density levels corresponding to adjacent ones of the portions in a predetermined image density area including an image density level corresponding to a boundary between an image density area where an image is formed using only the light toner and an image density area where an image is formed using both of the light toner and the dark toner, is smaller than that in a density area other than the predetermined image density area.
