Abstract:
A color image forming apparatus, comprising:a drum configured to have a photosensitive surface; an optical scanning mechanism configured to deflect a laser light beam modulated with image data per color to form a latent image on said photosensitive surface; a developer unit configured to contain a plurality of different color toners for developing said latent image formed on said photosensitive surface with a corresponding color toner into a color toner image; an intermediate transfer member configured to rotate in synchronism with rotation of said drum and to receive a color toner image developed using each of said different color toners to form on said intermediate transfer member a composite color toner image including multiple images of said different color toners overlaying on one another; a plurality of movement detecting mechanisms configured to detect respective movements of said drum and said intermediate transfer member; and a controller configured to control respective rotations of said drum and said intermediate transfer member using a detection of the plurality of movement detecting mechanisms.
