Abstract
An image forming apparatus includes a plurality of image forming sections that form a toner image on a medium to be fed using a developer containing toner and non-volatile oil, and a heating unit that is arranged on a downstream side of an image forming section, which is arranged on an upstream side in a feeding direction of the medium, and on an upstream side of an image forming section, which is arranged on a downstream side in the feeding direction, among the plurality of image forming sections, wherein the heating unit heats the toner on the medium to a melting temperature of the toner or higher.
Claims5
An image forming apparatus comprising:
- a plurality of image forming sections that form a toner image on a medium to be fed using a developer containing toner and non-volatile oil;
- and
- a heating unit that is arranged (1) on a downstream side of an image forming section arranged on an upstream side in a feeding direction of the medium, and (2) on an upstream side of an image forming section arranged on a downstream side in the feeding direction, among the plurality of image forming sections,
- wherein the heating unit heals the toner on the medium to a melting temperature of the toner or higher, and
- wherein a difference in solubility parameter (SP) value between toner and non-volatile oil contained in a developer, which is used in an image forming section on an upstream side of the heating unit in the feeding direction, among the developers of the plurality of the image forming sections, is 1.8 to 7.0.
