An image printing apparatus includes a control unit which controls a rotational speed of an image carrier; a detecting unit which detects data of the rotational speed; a storage unit which stores the rotational speeds up to n past rotation cycle of said image carrier; and a determining unit which determines whether a rotational speed difference between a latest rotational speed in a current rotation cycle and a rotational speed in n past rotation cycle before the current rotation cycle at a predetermined interval, which includes the same rotational position in respective rotation cycles and its near position, is more than a predetermined reference value, wherein said control unit controls the rotational speed of said image carrier by using the data of rotational speeds at a predetermined interval including the same rotational position in one or n past rotation cycle before the current rotation cycle, and further said control unit controls a rotational speed in a subsequent rotation cycle next to the current rotation cycle in accordance with a determination result obtained by said determining unit.
