    • The present invention relates to a toner composition for electrophotography, used for development of electrostatic image in electrophotography, electrostatic printing, etc., as well as to a process for producing such a toner composition. The toner composition of the present invention comprises a binder resin component [component (A)] and a coloring agent component [component (B)], wherein the binder resin component [component (A)] comprises a particular crosslinked aromatic polyester resin component [component (a-1)] and a particular linear aromatic polyester resin component [component (a-2)] and the proportions of the component (a-1) and the component (a-2) are 5 to 80% by weight [the component (a-1)] and 20 to 95% by weight [the component (a-2)] based on the total weight of the two components. The present invention can provide a toner composition for electrophotography, which is superior in grindability, wax dispersibility and mechanical durability, superior in blocking resistance and offset resistance, and superior in balance between fixing properties after development and development durability.
