Patent ID: 8837994

Claim:
A method for controlling an image forming apparatus including a correction unit for correcting positions of images, formed by a plurality of image forming units, based on a misregistration correction condition, the method comprising the steps of: forming pattern images in several colors on a plurality of photosensitive members; transferring the pattern images onto an image bearing member; detecting an amount of misregistration of the pattern images transferred onto the image bearing member; saving a misregistration correction condition based on the detected amount of misregistration; and determining whether to form the pattern images based on a predetermined condition, the predetermined condition including a first condition and a second condition, wherein, in a case where it is determined to form the pattern images based on the first condition, the misregistration correction condition based on the detected amount of misregistration is not saved when the detected amount of misregistration is larger than a first tolerance, and in a case where it is determined to form the pattern images based on the second condition, the misregistration correction condition based on the detected amount of misregistration is not saved when the detected amount of misregistration is larger than a second tolerance different from the first tolerance.
