Abstract: A multi-color image forming apparatus, for forming a superimposed multi-color image on a transfer material, includes: a latent image bearing member; device for forming a latent image on the image bearing member; plural developing devices containing different color developers for developing the latent image in different colors; device for accommodating the plural developing devices; guiding device for guiding the developing device between a first position within the accommodating device and a second position adjacent the image bearing member; driving device for moving the developing device between the first position and the second position for exchanging the developing device at the second position; device for discriminating the plural developing devices; and a second developing device disposed adjacent the image bearing member at a different position; wherein when plural colors are selected for development; a discrimination is made as to whether the developing device containing the developer of the selected color is at the first position or not, and if so, the developing device located at the first position is operated before the other of the plural developing devices, irrespective of the order of the selection.
