Abstract: An image forming apparatus includes a registration unit which performs color registration correction by using a registration sensor, an image forming unit which forms a preset first mark whose range is greater than a range recognizable by the registration sensor on an image forming medium, and a storage which stores a specific area of an image forming medium recognizable by the registration sensor by using the formed preset first mark. The image forming apparatus further includes a controller which controls the image forming apparatus to form a preset second mark to perform color registration correction within a range recognizable by the registration sensor by using information regarding the specific area which was previously stored in the storage, and the controller controls the registration unit to perform color registration correction by using the formed preset second mark.
