Abstract
The development roller adheres toner to an electrostatic latent image on the photo conductor drum in order to develop a toner image. The pattern image generating unit develops two pattern images that are two sets of plural test patches for calibration on the photo conductor drum. Each one of the pattern images includes the test patches corresponding to densities in gradation. Further, the pattern image generating unit sets an interval between a top of the first pattern image and a top of the second pattern image so that a remainder for the interval divided by a density fluctuation pitch is larger than a length of the test patch. The density fluctuation pitch is the product of a periphery length of the development roller and a ratio between a rotating speed of the development roller and a rotating speed of the photo conductor drum.
