Abstract
An image forming apparatus includes an adjustment sequence controller that causes first to third adjustment processes to be executed. In the first adjustment process, if a second registration mark having reduced calculation errors of shifts of toner-image formation positions as compared with those of a first registration mark is formed in a normal way, the toner-image formation positions are adjusted by using the second registration mark. In the second adjustment process, if the second registration mark is not formed in the normal way, the toner-image formation positions are adjusted by using the first registration mark. In the third adjustment process, if the second registration mark is formed in the normal way after the second adjustment process, the toner-image formation positions are adjusted by using the second registration mark.
