ABSTRACT:
A first pattern having lines of a first color and a second pattern having lines of a second color are formed on an image transferring member near the side edges thereof. Each of the first and second color lines are sequentially detected by a sensor. Absolute values of time differences between detection of first lines and corresponding second lines are calculated. This process of detection of the time differences is repeated several times while changing the rotational phase of the an image carrying member for the second color. A position where the time difference is relatively lowest or even the minimum is selected.
