A magnetic carrier and a two-component developer are provided which have remedied blank areas, fog after leaving, carrier sticking during running, and image density variations before and after running. A magnetic carrier which has magnetic carrier particles having at least porous magnetic core particles and a resin, characterized in that , where, in a reflected electron image of cross sections of the magnetic carrier particles as photographed with a scanning electron microscope, straight lines that divide a cross section of a magnetic carrier particle into 72 at intervals of 5° are drawn from a reference point of the cross section thereof toward the surface of the magnetic carrier particle, the number A of straight lines along which the resin is in a thickness of from 0.0 to 0.3 µm as found by measuring the distance from the surface of the magnetic carrier particle to the surface of a porous magnetic core particle on the straight lines is from 7 to 36 lines, based on 72 lines in total number of the straight lines, and the number B of straight lines along which the resin is in a thickness of from 1.5 to 5.0 µm as found by measuring the distance from the surface of the magnetic carrier particle to the surface of the porous magnetic core particle on the straight lines is from 7 to 36 lines, based on 72 lines in total number of the straight lines. |
