Abstract:
1. An image forming apparatus, comprising: a plurality of image forming parts; a moving medium continuously moving on said plurality of image forming parts according to an arrangement of color orders of the plurality of image forming parts; first test image forming means for forming a first test image on the moving medium by using the plurality of image forming parts in a first color order; density measuring means for measuring a density of the test image formed on the moving medium; second test image forming means for forming a second test image on the moving medium by setting a first image forming condition in a corresponding image forming part based on a result of measuring a density of the first test image using the density measuring means and by using the corresponding image forming pan based on the first image forming condition in a second color order; and control means for controlling image forming processing in the plurality of image forming parts according to the first and second image forming conditions by setting a second image forming condition in each of the plurality of image forming parts based on a result of measuring a density of the second test image using the density measuring means, wherein the first test image and the second test image are formed within predetermined dimensions by applying specific color orders to the first and second color orders, respectively; and wherein the plurality of image forming parts form images having different colors from each other and a color order of formed color images differs between the first test image and the second test image.
