摘要： An exposure unit which exposes photoconductive drums having rotary axes thereof arranged parallel to each other on a single plane by light beams, includes one or more polygon mirrors each having a plurality of reflection surfaces, where the one or more polygon mirrors rotate about a common rotary axis. Each light beam is deflected by the one or more polygon mirrors and scans the surface of a corresponding photoconductive drum. The common rotary axis is separated from the rotary axes of the photoconductive drums by identical distances along respective normals which are perpendicular to both the common rotary axis and the rotary axes of the photoconductive drums.

摘要： Sensors detect a displacement correction pattern image-formed on a transporting belt. A timing when the sensors execute a detecting operation is preliminary set depending on a tolerance in a layout or a dimension of a portion where the displacement correction pattern is image-formed, detected. Based on the detected timing detected by the sensors, the preliminary set timing is modified.

摘要： 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.
