An object of the present invention is to achieve an accurate image with a mass per toner area smaller than before, to obtain a color gamut comparable to printing, to cope with high speed, and to form an image with stable color even in long-term use. It is to provide a two-component developer. A two-component developer containing a cyan toner and a magnetic carrier, wherein the cyan toner comprises i) the cyan toner concentration in the chloroform solution of the cyan toner as Cc (mg / ml), and the wavelength of the solution. When the absorbance at 712 nm is A712, the relationship between Cc and A712 satisfies 2.00 <A712 / Cc <8.15, and ii) the brightness L * and saturation C * obtained in the powder state of the cyan toner are 25.0≤L *. ≤ 40.0 and 50.0 ≤ C * ≤ 60.0, and iii) the absolute value of the triboelectric charge of the cyan toner measured by the two-component method using the cyan toner and the magnetic carrier is 50 mC / kg or more and 120 mC / kg or less. The objective can be achieved by the two-component developer characterized by the above-mentioned. |
