There is provided an image forming apparatus. The image forming apparatus, after controlling so as to develop the developer image representing the predetermined image formed a plurality of times in the same location on an image carrier by an exposing component, controls such that without performing exposure with the exposing component, the developer image, developed on the image carrier by the developing component applying a biasing voltage to the developer so as to adhere the developer to the image carrier including to the same location on the image carrier, is transferred to the transfer component and detects whether or not a ghost image is generated by comparing the density detected by a detecting component at a position of a transfer body corresponding to the same location of the image carrier to a reference density.
