The present invention provides a toner capable of efficiently taking in irradiation energy and fixing at a high temperature in a short time, and an energy-saving and practical image forming apparatus using the toner. The toner of the present invention is a toner having a capsule composed of a core material and a first shell (or covering shell) material that covers the core material, and the core material contains water, urea, and toner. This is a solution containing a solvent that dissolves or swells the constituent resin. When the toner is fixed, microwaves are irradiated to generate heat and elute from the shell to fix the toner on the recording medium. The image forming apparatus includes a microwave irradiation device and uses the toner. [Selection] Figure 1 |
