Abstract
Conventionally, it has been impossible to adjust a transportation direction magnification correspondingly to jobs, causing an image to be formed in an unintended size, while the transportation direction magnification for the image formed on the sheet varies with jobs. A controller included in an image forming apparatus selects an image adjustment chart used to adjust a transportation direction magnification that varies with job conditions of a job to be executed currently in a transportation direction of images transferred to sheets by a transferrer. The controller adjusts the transportation direction magnification for images formed by an image former based on the image adjustment chart formed on a sheet by the image former.
