ーに関する。 The present invention relates to a toner having toner particles obtained by melt-kneading a mixture containing a binder resin and a wax and pulverizing the obtained kneaded product.
The binder resin contains a crystalline polyester resin and an amorphous polyester resin,
The content of the crystalline polyester resin is 1.0 part by mass or more and 15.0 parts by mass or less with respect to 100 parts by mass of the amorphous polyester resin,
The amorphous polyester has a softening point Tm (A) of 80 ° C. or higher and 120 ° C. or lower,
The contact angle Θ (A) of the wax heated to 130 ° C. with respect to the amorphous polyester resin is 16 ° or more and 30 ° or less,
The contact angle Θ (B) of the wax heated to 130 ° C. with respect to the crystalline polyester resin is 5 ° or more and 13 ° or less,
On the surface of the toner particles, no machine microparticles have fixed by hot air treatment,
The present invention relates to a toner characterized in that the coverage of the toner particle surface with the inorganic fine particles is 15% or more.
