PROBLEM TO BE SOLVED: To provide a toner having excellent durability even in a non-contact fixing system and continuously giving high quality images and to provide a two-component developer containing the toner. SOLUTION: The toner contains a binder resin and a colorant and has externally added inorganic fine particles. The toner has a storage modulus (25 mm parallel plates) of≤7×10<SP>4</SP>Pa at 100°C, a storage modulus (7.9 mm parallel plates) of 3×10<SP>8</SP>to 1×10<SP>9</SP>Pa at 60°C and a storage modulus (7.9 mm parallel plates) of 7×10<SP>6</SP>to 3×10<SP>8</SP>Pa at 70°C, and the inorganic fine particles have a BET specific surface area of≤30m<SP>2</SP>/g.
