Image forming apparatus
An image forming apparatus includes an image forming section. The image forming section includes a first toner image forming unit and a second toner image forming unit. The first toner image forming unit forms a sublimation toner image with use of a sublimation toner. The sublimation toner includes a sublimation dye. The second toner image forming unit forms a non-sublimation toner image with use of a non-sublimation toner. The non-sublimation toner does not include the sublimation dye. The image forming section transfers the non-sublimation toner image and the sublimation toner image in this order on a print medium and thereby causes a transfer region of the non-sublimation toner image and a transfer region of the sublimation toner image to be overlapped with each other.
1. An image forming apparatus comprising
an image forming section including
a first toner image forming unit forming a sublimation toner image with use of a sublimation toner, the sublimation toner including a sublimation dye, and
a second toner image forming unit forming a non-sublimation toner image with use of a non-sublimation toner, the non-sublimation toner not including the sublimation dye,
the image forming section transferring, on a print medium, the sublimation toner image formed by the first toner image forming unit, and transferring, on the print medium, the non-sublimation toner image formed by the second toner image forming unit, and
the image forming section transferring the non-sublimation toner image and the sublimation toner image in this order on the print medium and thereby causing a transfer region of the non-sublimation toner image and a transfer region of the sublimation toner image to be overlapped with each other.
2. The image forming apparatus according to claim 1 , wherein a disposed amount of the formed non-sublimation toner image is equal to or greater than 0.10 milligrams per square centimeter.
3. The image forming apparatus according to claim 2 , wherein the disposed amount of the formed non-sublimation toner image is equal to or greater than 0.20 milligrams per square centimeter.
4. The image forming apparatus according to claim 3 , wherein the disposed amount of the formed non-sublimation toner image is equal to or greater than 0.38 milligrams per square centimeter.
5. The image forming apparatus according to claim 2 , wherein the disposed amount of the formed non-sublimation toner image is equal to or smaller than 0.65 milligrams per square centimeter.
6. The image forming apparatus according to claim 1 , wherein the non-sublimation toner includes no colorant and includes polyester-based resin.
7. The image forming apparatus according to claim 6 , wherein the non-sublimation toner comprises a clear toner.
8. The image forming apparatus according to claim 1 , wherein
the image forming section further includes an intermediate transfer medium, and
the image forming section transfers the sublimation toner image and the non-sublimation toner image in this order onto the intermediate transfer medium, and thereafter transfers the non-sublimation toner image and the sublimation toner image in this order from the intermediate transfer medium onto the print medium.
9. The image forming apparatus according to claim 1 , further comprising a fixing section that fixes, to the print medium, the non-sublimation toner image and the sublimation toner image both transferred onto the print medium by the image forming section.
10. The image forming apparatus according to claim 9 , wherein
the image forming section stacks the non-sublimation toner image and the sublimation toner image in this order on the print medium, and
the fixing section collectively fixes, to the print medium, the non-sublimation toner image and the sublimation toner image both stacked on the print medium by the image forming section.
11. The image forming apparatus according to claim 1 , wherein the sublimation dye has a sublimation transfer property that causes the sublimation dye to move from the print medium to a non-print medium with use of thermal energy.
