Patent ID: 7794908

Claim:
A magnetic toner comprising: capsule type toner particles each having a toner base particle (A) and a surface layer (B) on a surface of the toner base particle (A), wherein the toner base particle (A) comprises at least a binder resin (a) mainly formed of a polyester, a magnetic substance, and a wax, the surface layer (B) comprises a resin (b), and the resin (b) comprises a resin selected from the group consisting of a vinyl resin (b2), and a urethane resin (b3); a glass transition temperature Tg(a) of the binder resin (a) and a glass transition temperature Tg(b) of the resin (b) satisfy a relationship represented by the following formula (1), Tg ( a )< Tg ( b ) (1); a magnetization (στ) in an external magnetic field of 79.6 kA/m of the magnetic toner is 12 Am 2 /kg or more and 30 Am 2 /kg or less; and an average circularity of the magnetic toner is 0.960 or more and 1.000 or less.
