Title:
TONER AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3738612
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the toner wide in a fixable temperature range and good in fixability and the manufacture of such a toner.
SOLUTION: This toner is obtained by melting fine resin grains comprising a crystalline substance and an amorphous polymer to attach them in an aqueous medium, and it is preferred that the crystalline substance has a melting point of 60°C to 130°C and a number average molecular weight of 1,500 to 15,000 and a melt viscosity of ≤100 dPa.s at a temperature of melting point +20°C. This toner is manufactured by preparing fine resin grains by emulsion polymerization of a radically polymerizable monomer solution and attaching the fine resin grains by melting them in the aqueous medium.
