IMAGE FORMING APPARATUS

An image forming apparatus includes a receiving part that receives multiple page images including a first page image and a second page image, a medium carrying part that carries the recording media, and an image forming part that forms images on the recording media carried by the medium carrying part based on the first and second page images processed by the image processing part. The image processing part determines one edge region of the first page image, which has the highest image density among four edge regions on the first page image, changes the orientation of the first page image such that the one edge region having the highest image density is arranged to be at the trailing side of the first page image, and changes the orientation of the second page image to the same orientation as that of the first page image.
