Abstract
An adjustment method for an image forming device, for adjusting image forming condition with respect to a sheet by using image forming means. The adjustment operation is performed in such a manner that: a first image, that is used for detecting scanning error of an image scanning device, is formed on an image carrying body and then transferred from the image carrying body to the sheet, the first image being formed over at least three corners of the sheet while extending outside the sheet. The sheet with the first image is scanned by the image scanning device to figure out a scanning error amount of the image scanning device, and a correction value of image forming condition of the image forming means is found in consideration of the scanning error amount. The image forming condition with respect to the sheet is modified based on the correction value.
