A controller controls transportation of the recording medium such that a first distance between a trailing edge of an image area of a preceding page of the two successive pages and a leading edge of an image area of a following page is equal to or longer than a second distance between the nip at a most upstream one of the image forming sections and the nip at a most downstream one of the image forming sections. Control may also be performed such that a first distance between a trailing edge of a preceding page of the two successive pages and a leading edge of a following page is equal to or longer than a second distance between the nip at a most upstream one of the plurality of image forming sections and the nip at a most downstream one of the plurality of image forming sections.
