A density control device includes an image forming unit for forming a sample image having a predetermined density onto a recording medium, a density detecting unit for detecting the density of the surface of the recording medium, and a control unit for causing the density detecting unit to detect a first density of an area where no sample image is formed on the recording medium and a second density of an area where any sample image is formed, and determining the operation conditions of the image forming unit, based on a contrast value between the first density and the second density which have been detected.
