摘要:
A toner for electrostatic charge image development is a toner for electrostatic charge image development including toner particles containing a binder resin and an external additive, wherein the binder resin contains a crystalline polyester resin and an amorphous polyester resin, the external additive includes Al—Si composite oxide particles, and a Si element content of the Al—Si composite oxide particles is in the range of 50 to 90 mass % and a Si element ratio on surfaces of the Al—Si composite oxide particles is in the range of 3 to 35 at %.
