    Abstract: Hollow toner and a process of preparing the same are provided. The hollow toner has a hollow sphere shape, wherein an outer layer surrounding the hollow sphere includes a polymer, a wax and a pigment. The hollow toner has excellent fixing properties under low energy and low pressure, and can be efficiently used at high-speed fixing. Also, a small amount of the hollow toner is consumed. Thus, the hollow toner can be efficiently applied to various apparatuses of forming an image such as a two-component low-temperature printer and super high-speed printer, and the hollow toner can be prepared by using a relatively simple process.
