Abstract: A bias correction is carried out before a color registration correction is carried out so as to stabilize the running state of an intermediate transfer belt, thereafter the bias correction ceases and the color registration correction is carried out.

Abstract: An image forming apparatus includes: a rotating belt which rotates around a roller; a drive section which rotates the belt; a detection section which detects a position of the belt in a width direction; a moving section which moves the belt in the width direction; a control section which corrects a deviation of the belt by controlling the moving section. The control section conducts a preparatory operation in which the control section changes an amount of control to be given to the moving section under the condition where the belt is rotated to obtain a correction data showing a relation between the amount of control and a change of a position of the belt in the width direction detected by the detection section, stores the correction data in a memory section, and then corrects the deviation based on the correction data stored in the memory section.

Abstract: A full-color image forming apparatus for forming a toner image for each color on each image carrier, and for transferring the toner image onto a sheet, including: an image forming section for forming a correcting toner image for each color on a portion of an image carrier, wherein the portion corresponds to an interval between the successive sheets; and a control section for conducting a correcting operation of the toner image for each color, based on the correcting toner image which is formed by the image forming section, wherein, when the image forming section is possible to conduct an operation, if the image forming section is controlled to interrupt the correcting operation to use the correcting toner image yet to be formed, the control section controls the image forming section to form the residual correcting toner image, before the control section controls the image forming section to stop the operation.
