Toner and its manufacturing method |
| abstract |
PROBLEM TO BE SOLVED: To provide a toner excellent in low temperature fixing property, hot offset resistance and scratch resistance of a fixed image. SOLUTION: The toner has toner particles containing a binder resin, a crystalline polyester and calcium carbonate particles, and the crystalline polyester contains a unit derived from an aliphatic diol and an acid unit derived from an aliphatic dicarboxylic. The ester group concentration Ec of the crystalline polyester is 27% by mass or more and 50% by mass or less, and the amount Ma of the calcium carbonate particles contained in the toner particles is 3% by mass or more and 40% by mass or less, and is contained in the toner particles. A toner in which the ratio (Ma / Mc) of the content Ma of the calcium carbonate particles contained in the toner particles to the content Mc of the crystalline polyester is 0.2 or more and 20 or less on a mass basis.
