Image forming apparatus including image forming units that form a developer image and selectively form a mark image
An image forming apparatus includes an image forming device which forms an image on a recording medium and an image scanning device which transmits scanned image data to the image forming device. The image forming device includes a receiver, a first image forming unit, a second image forming unit, and a controller. The receiver 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 forms a developer image based on the input image data on the recording medium. The second image forming unit forms a mark image on the recording medium. The controller determines whether to make the second image forming unit form the mark image or not depending on a type of a transmission source of the input image data.
1. An image forming apparatus comprising:
an image forming device which forms an image on a recording medium; and
an image scanning device which transmits scanned image data generated by optically scanning an image to the image forming device; wherein:
the image forming device includes:
a receiver which receives at least one of external image data transmitted from an external device and the scanned image data transmitted from the image scanning device as input image data;
a first image forming unit which forms a developer image based on the input image data on the recording medium;
a second image forming unit which forms a mark image on the recording medium; and
a controller which determines whether to make the second image forming unit form the mark image or not depending on a type of a transmission source of the input image data.
2. The image forming apparatus according to claim 1 , wherein the controller makes the second image forming unit form the mark image when the type of the transmission source is the image scanning device.
3. The image forming apparatus according to claim 2 , wherein:
when the type of the transmission source is the external device, the external device is at least one of a facsimile machine, a personal computer, and an information storage device, and
when the type of the transmission source is the external device, the mark image indicates that the type of the transmission source is at least one of the facsimile machine, the personal computer, and the information storage device.
4. The image forming apparatus according to claim 3 , wherein the mark image includes at least one of a letter, a figure, and a symbol indicating that the type of the transmission source is the external device.
5. The image forming apparatus according to claim 2 , wherein the mark image includes at least one of a letter, a figure, and a symbol indicating that the type of the transmission source is the image scanning device.
6. The image forming apparatus according to claim 2 , wherein the controller does not make the second image forming unit form the mark image when the type of the transmission source is the external device.
7. The image forming apparatus according to claim 2 , wherein the controller makes the second image forming unit form the mark image according to the type of the transmission source of the input image data.
8. The image forming apparatus according to claim 1 , wherein the second image forming unit forms the mark image in a printable region on the recording medium in which the first image forming unit forms the developer image.
9. The image forming apparatus according to claim 1 , wherein the second image forming unit forms the mark image in a marginal region on the recording medium other than a printable region in which the first image forming unit forms the developer image.
10. An image forming apparatus comprising:
an image forming device which forms an image on a recording medium; and
an image scanning device which transmits scanned image data generated by optically scanning an image to the image forming device; wherein:
the image forming device includes:
a receiver which receives at least one of external image data transmitted from an external device and the scanned image data transmitted from the image scanning device as input image data;
a first image forming unit which forms a developer image based on the input image data on the recording medium;
a second image forming unit which forms a mark image on the recording medium; and
a controller configured to select a type of the mark image to be formed by the second image forming unit depending on a type of a transmission source of the input image data.
11. The image forming apparatus according to claim 10 , wherein the mark image is formed with luminescent developer containing a luminescent material, the luminescent material emitting visible light.
12. The image forming apparatus according to claim 11 , wherein the luminescent developer is fluorescent toner which emits light by being irradiated with ultraviolet rays.
13. The image forming apparatus according to claim 10 , wherein the mark image includes at least one of a letter, a figure, and a symbol indicating the type of the transmission source.
14. The image forming apparatus according to claim 10 , wherein the mark image includes at least one of a letter, a figure, and a symbol indicating that the type of the transmission source is at least one of the image scanning device, a facsimile machine, a personal computer, and an information storage device.
15. The image forming apparatus according to claim 10 , wherein the second image forming unit forms the mark image in a printable region on the recording medium in which the first image forming unit forms the developer image.
16. The image forming apparatus according to claim 10 , wherein the second image forming unit forms the mark image in a marginal region on the recording medium other than a printable region in which the first image forming unit forms the developer image.
