Magnetic carrier and two-component developer

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

• said toner has toner particles containing at least a binder resin, a release agent and a colorant, and the transmittance of light having a wavelength of 600 nm through a dispersion prepared by dispersing said toner in an aqueous 45% by volume methanol solution is from 10% to 70%;
• and
• said magnetic carrier has a BET specific surface area (BET 1) from 0.02 m2/g to 0.20 m2/g as measured by a BET method, and comprises carrier particles, wherein:
• each carrier particle comprises a carrier core and a coat material for coating the carrier core,
• the carrier core comprises at least a binder resin and magnetic particles dispersed in the binder resin,
• the coat material has a coat resin,
• a ratio (A) of a fluorine element abundance ratio (Fatom) to a carbon element abundance ratio (Catom), Fatom/Catom, at a surface of said carrier particle is from 0.10 to 0.85, and a ratio ((A)/(B)) of a ratio (A) of fluorine element abundance ratio (Fatom) to a carbon element abundance ratio (Catom), Fatom/Catom, at a surface of said carrier particle to a ratio (B) of a fluorine element abundance ratio (Fcalc) to a carbon element abundance ratio (Ccalc) that is theoretically calculable from molecular structure of the coat resin, Fcalc/Ccalc is from 1.01 to 3.00.
