  • Patent number: 10960699
    Abstract: 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.
