Abstract: An image forming apparatus includes an image forming device and an image scanning device. The image forming device forms an image on a recording medium on the basis of image information of an image scanning target scanned by the image scanning device including a conveyance device and a plurality of image sensors. The conveyance device includes a movable surface which moves to convey the scanning target in contact therewith to have the scanning target pass through a predetermined image scanning position. The image sensors are arranged in a perpendicular direction to a conveyance direction of the scanning target and at positions facing the conveyance device across the predetermined image scanning position to scan the scanning target and obtain the image information. Adjacent two of the image sensors have mutually overlapping scanning areas in the perpendicular direction, and have mutually different positions in the conveyance direction.
