COLOR TONER COMPOSITION HAVING HIGH TRANSFER EFFICIENCY AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A toner composition and a manufacturing method thereof are provided to improve the stability of electrification property and the efficiency of transfer of the toner composition. CONSTITUTION: The toner composition having a high transfer efficiency consists of toner particle having a binder resin, a colorant, and an electrification control agent; and hydrophobic silica and titanium oxide added to the surface of the toner particle. One of the hydrophobic silica has a specific surface area of 20 to 80 square meters per gram, the other one has a specific surface area of 130 to 230 square meters per gram.
