发明名称 Toner
摘要 The present specification discloses a toner for electrophotography. This toner comprises two or more kinds of binder resins, and is characterized in that the surface tension of each of the binder resins and the melt viscosity thereof, both at a temperature of 200 DEG C., are respectively below 30 dyne/cm and 100 poises or more, and the melt viscosity thereof and the storage modulus thereof, both at a temperature of 125 DEG C., are respectively below 5000 poises and below 40000 dyne/cm2, a toner comprising a surface tension reducing agent and a binder resin. Because the melt viscosity of the binder resin at a temperature of 200 DEG C. is 30 poises or more, a toner having an excellent void resistance can be obtained without a worsening of the fixability and blocking resistance thereof.
