An image forming apparatus (1) includes an image forming device (100) which forms an image on a recording medium and an image scanning device (200) which transmits scanned image data to the image forming device (100). The image forming device (100) includes a receiver (110), a first image forming unit (2Y, 2M, 2C, 2K), a second image forming unit (2V), and a controller (120). The receiver (110) receives at least one of external image data transmitted from an external device and the scanned image data as input image data. The first image forming unit (2Y, 2M, 2C, 2K) forms a developer image based on the input image data on the recording medium. The second image forming unit (2V) forms a mark image on the recording medium. The controller (120) determines whether to make the second image forming unit (2V) form the mark image or not depending on a type of a transmission source of the input image data. |
