(57) [Problem] To provide a two-component developer which is free from toner scattering and background stain on an image, and has excellent reproducibility of fine lines and halftones. A component developer is provided. SOLUTION: The two-component developer of the present invention comprises at least a magnetic toner composed of a binder resin and a magnetic substance, and a magnetic carrier composed of at least a magnetic substance. The particle diameter distribution of the magnetic toner is such that the weight-average particle diameter is 6.0 to 8.0 μm, the magnetic toner particles having a weight average particle diameter of 5 μm or less are 40 to 80% by number, and The magnetization of the magnetic toner in a 5k Oersted magnetic field is 10 -25 emu / g, and the magnetization in a 1 k Oe magnetic field is 7-20 emu / g. |
