ABSTRACT:
An image forming apparatus has: a photosensitive drum onto which images are formed; and a primary transfer roller which sequentially forms the color images onto the photosensitive drum by using a plurality of developing devices having different color developers and transfers the color images formed on the drum onto a transfer member or a recording medium. Order of forming the images onto an image bearing member on a photosensitive member is switched based on a use amount of each of the plurality of developing devices.
