Abstract

PURPOSE: To prevnet the offset of a toner to a heat fixing roll by using noncrystalline polyester and crystalline polyester as the binder resin of the toner.
CONSTITUTION: 50W95pts.wt. Noncrystalline polyester with ≥40°C glass transition temp., 80W150°C softening point and 1,000W10,000 number average mol. wt. and 50W5pts.wt. crystalline polyester with ≥0°C glass transistion temp., 110W220°C m.p. and 8,000W40,000 number average mol. wt. are melted, mixed, pulverized, mixed with carbon black, pulverized with a ball mill, melted, and mixed with a roll mill. This mixtuer is cooled, finely pulverized, and classified to obtain a toner, When the glass transistion temp., softening point and mol. wt. of each of the resins used are without the above-mentioned ranges, the resulting toner has defects such as the occurrence of blocking in storage, or of excess heat generated by fixing.
