Abstract:
1. An image forming device comprising: a plurality of photoconductors each corresponding to one of a plurality of colors; a plurality of exposure units, each of the exposure units forming a latent electrostatic image on a corresponding one of the photoconductors; a plurality of developing units each corresponding to one of the plurality of colors, each of the developing units developing the latent electrostatic image formed on the corresponding one of the photoconductors into a developer image; an image support member that supports the developer image; a transfer unit that transfers the developer images each developed by one of the developing units onto the image support member; and a density detector that detects a density of the developer image, wherein during printing, the transfer unit transfers the developer images in each of the plurality of colors such that the developer images are superimposed on the image support member thereby to produce a multicolor image; and during density detection, the transfer unit transfers the developer images in each of the plurality of colors to mutually different positions of the image support member within a range of the image support member that is less than a range necessary for printing an image corresponding to a maximum sheet size upon which the image forming device is capable to print, and the density detector detects the density of each developer image supported on the image support member.
