METHOD FOR PREPARING TONER

摘要

PURPOSE: A method for manufacturing toner is provided to improve fixation characteristic of the toner at low temperatures. CONSTITUTION: A method for manufacturing toner includes the following: a polyester resin dispersing solution, a coloring agent dispersing solution, and a wax dispersing solution are mixed; a coagulating agent is added into the mixed solution to coagulate toner particles; and the coagulated toner particles are combined. The polyester resin dispersing solution includes the mixture of two or more polyester resins. The max peak position of the mixture is in a range between 40,000 and 80,000. The number average molecular weight of the mixture is in a range between 10,000 and 20,000. The weight average molecular weight of the mixture is in a range between 25,000 and 40,000. The polyester resins include polyester resins without a sulfonic acid group.
