ABSTRACT:
An image forming method exposes image bearing members by simultaneously reflecting light beams from light sources, corresponding to different colors, by different reflection surfaces of a polygon mirror which has reflection surfaces and is rotated in one direction, transforms electrostatic latent images formed on each of the image bearing members into toner images for correction, transfers the toner images on each of the image bearing members in an overlapping manner onto a transfer body that is transported in a transport direction, and calibrates overlapping positions of the toner images based on an optical detection of the toner images on the transfer body. The toner images are arranged at positions on the transfer body such that the toner images of different colors have no overlap therebetween even if the toner images shift in a direction perpendicular to the transport direction due to a color registration error.
