    摘要： There is provided a toner having good charging characteristics that is composed of a core region and a thin shell in which a charge control agent is densely distributed so as to improve charging characteristics of the toner, and a method for manufacturing the same. The method for manufacturing a toner having a bi-layered structure includes: producing a toner core using a suspension polymerization method; preparing a suspension of toner particles having a core-shell structure by forming a rigid shell on a surface of the toner core; and recovering the toner particles from the suspension as a post-processing operation.
