摘要： A method of preparing a toner includes: adding a first external additive having an average primary particle diameter of between about 30 nm and 200 nm to toner particles including a binder resin and a colorant and stirring the first external additive with the toner particles to form a first external additive layer on the surfaces of the toner particles; and adding a second external additive having an average primary particle diameter between about 5 nm and 30 nm to the toner particles having the first external additive layer and stirring the second external additive with the toner particles to form second external additive layers on the first external additive layers. A stirring line speed of the first external additive is less than a stirring line speed of the second external additive. The method of preparing a toner increases the endurance of the toner and prevents a developing member from being contaminated. External additives having different average primary particle diameters are sequentially added to toner particles including a binder resin and a colorant so that external additives having greater average primary particle diameters are uniformly coated on the surface of the toner particles. Accordingly, a uniform charge and the fluidity of the toner are improved and contamination of a charge roller and other developing members due to a separation of the external additives is prevented.
