摘要： A positional error detection method forms, on a belt which is transported in a transport direction, positional error detection marks for detecting a positional error between image positions of first and second colors, detects the positional error detection marks on the belt, and computes the positional error based on the detected positional error detection marks. The positional error detection marks include first and second marks which are inclined in mutually opposite directions with respect to the transport direction, and third marks which are perpendicular to the transport direction.

摘要： An optical writing controller that controls a light source to expose a photoconductor and forms an electrostatic latent image on the photoconductor calculates a correction value for correcting a superimposing position where the developed images for different colors developing each of the electrostatic latent images formed on each of the multiple photoconductors are superimposed based on the detection signal output by a pattern detection sensor that detects a pattern for correcting the superimposing position, controls the multiple light sources to draw a predetermined pattern repeatedly in the sub-scanning direction so that stepwise patterns whose width in the main scanning direction varies with repetition are formed, and determines the width in the main scanning direction of the patterns for correcting based on the strength of the detection signal output by the pattern detection sensor.

摘要： An image forming method exposes image bearing members by simultaneously reflecting light beams corresponding to different colors by different reflection surfaces of a polygon mirror, transforms electrostatic latent images formed on the image bearing members into toner images for correction, transfers the toner images in an overlapping manner onto a transfer body, and calibrates overlapping positions of the toner images based on an optical detection of the toner images. 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. Two first toner images simultaneously formed by two corresponding light beams reflected by one reflection surface of the polygon mirror are arranged adjacent to each other in a transport direction of the transfer body, and are sandwiched by two second toner images simultaneously formed by the two corresponding light beams reflected by the one reflection surface of the polygon mirror along the transport direction.
