摘要： A process for producing a wherein an aminium salt infrared light absorber and a positive charge control agent are used in combination while preventing a mutual reaction therebetween. In this toner, the physical contact of the aminium salt compound with the positive charge control agent is avoided (e.g., by separately adding them to respective two separated phases of a binder resin), or alternatively use is made of such a combination of confounds as will not cause a mutual reaction (e.g., a common anion is used).

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.degree. 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.degree. C., are respectively below 5000 poises and below 40000 dyne/cm.sup.2, 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.degree. 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.
