PROBLEM TO BE SOLVED: To provide toner that achieves low-temperature fixability, an excellent heat-resistant storage property, and durability at higher levels.SOLUTION: Toner has toner particles containing a graft polymer. The graft polymer contains a crystalline polyester position and an amorphous vinyl polymer position. The crystalline polyester position has a unit derived from a specific monomer (a) and a unit derived from a specific monomer (b). The unit derived from the monomer (b) has a content percentage X (mol%), which is calculated from a specific expression, of 1.0 mol% or more and 24 mol% or less. A melting point of the graft polymer is 50°C or more and 85°C or less.SELECTED DRAWING: None |
