Toner and two-component developer

A two-component developer comprising a toner and a magnetic carrier, wherein:

• the toner comprises toner particles each comprising at least a binder resin, a colorant, and a releasing agent, and inorganic fine particles;
• the binder resin comprises at least a polyester unit;
• a weight average particle diameter of the toner is in a range of 3.0 to 6.5 μm;
• an average circularity of particles in the toner each having a circle-equivalent diameter of 2 μm or more is in a range of 0.920 to 0.945;
• a BET specific surface area of the toner is in a range of 2.1 to 3.5 m2/g;
• a permeability of light of a wavelength of 600 nm in a liquid prepared by dispersing the toner in a 45 vol % aqueous solution of methanol is in a range of 30 to 80%;
• and
• the magnetic carrier comprises:
• magnetic core particles comprising a magnetic material;
• and a coating layer formed on surfaces of the magnetic core particles by using a resin, and a number average particle diameter of the magnetic carrier is in a range of 15 to 80 μm.
