Abstract

In accordance with an embodiment, an image forming apparatus comprises an image forming section and a specific light source. The image forming section forms an image on an image receiving medium with a specific material which emits visible light through irradiation by specific light. The specific light source emits the specific light to the image receiving medium at a downstream side of the image forming section in a conveyance direction of the image receiving medium.

First claim

What is claimed is:

1. An image forming apparatus, comprising:
an image forming section configured to form an image on an image receiving medium with a specific material which emits visible light through irradiation by specific light;
a specific light source configured to emit the specific light to the image receiving medium at a downstream side of the image forming section in a conveyance direction of the image receiving medium; and
a discharge tray to which the image receiving medium is discharged at the downstream side of the image forming section in the conveyance direction of the image receiving medium, wherein
the specific light source emits the specific light to the image receiving medium discharged to the discharge tray.

2. The image forming apparatus according to claim 1 , further comprising
a discharge mechanism configured to discharge the image receiving medium to the discharge tray so that the specific light is emitted to a printing surface of the image receiving medium.

3. The image forming apparatus according to claim 2 , further comprising
a discharge control section configured to control printing and discharge operation executed to a plurality of the image receiving media in such a manner that the image receiving media are discharged to the discharge tray in order starting from a final the image receiving medium at the time a plurality of the image receiving media is discharged.

4. The image forming apparatus according to claim 1 , wherein
the specific material comprises a UV toner; and
the specific light source emits a UV light.

5. The image forming apparatus according to claim 1 , further comprising
a mode selection section capable of selecting a UV print mode for forming an image on the image receiving medium with the specific material and an ordinary print mode for forming an image on the image receiving medium with an ordinary material that is visually recognizable with visible light.

6. The image forming apparatus according to claim 5 , further comprising
an ordinary light source configured to emit visible light to the image receiving medium; and
a light source switching section capable of switching between the specific light source and the ordinary light source.

7. The image forming apparatus according to claim 1 , wherein
the discharge tray is comprised in a main body of the image forming apparatus.

8. The image forming apparatus according to claim 1 , further comprising
an irradiation timing control section configured to control timing at which the specific light is emitted to the image receiving medium immediately after the image receiving medium is discharged to the discharge tray.

9. The image forming apparatus according to claim 1 , wherein
the specific light source emits the specific light towards the image receiving medium from an outlet of the image receiving medium.

10. An image forming method, comprising:
forming an image on an image receiving medium with a specific material which emits visible light through irradiation by specific light;
emitting the specific light to the image receiving medium at a downstream position in a conveyance direction of the image receiving medium;
discharging the image receiving medium to a discharge tray at the downstream side in the conveyance direction; and
emitting the specific light to the image receiving medium on the discharge tray.

11. The image forming method according to claim 10 , wherein the specific light has a wavelength from 10 nm to 380 nm.

12. The image forming method according to claim 10 , wherein the visible light has a wavelength from 400 nm to 700 nm.

13. The image forming method according to claim 10 , wherein the specific material comprises a UV toner and the specific light is UV light.

14. The image forming method according to claim 10 , further comprising
forming an image on the image receiving medium with an ordinary material that is visually recognizable with visible light.

15. The image forming method according to claim 14 , further comprising
emitting visible light to the image receiving medium; and
switching between emitting specific light and emitting ordinary light.

16. The image forming method according to claim 10 , further comprising
controlling a timing at which the specific light is emitted to the image receiving medium immediately after the image receiving medium is discharged to the discharge tray.
