Provides a blank, left after blurring, upon attachment of the carrier durability, improve the image density variations before and after the durability test in the magnetic carrier and two-component developer. As a magnetic carrier having magnetic carrier particles containing a porous magnetic core particles with the resin at least, taken by a scanning electron microscope on the reflected electrons of the cross-section of the magnetic carrier particles, the magnetic carrier from the reference point of the cross-section of the magnetic carrier particles when toward the surface of the particle 72 be equally divided by the straight line geueoteul 5 ° intervals, the one or more 0.0㎛ thickness of the resin measured by the distance to the surface of the porous magnetic core particles from a surface of the magnetic carrier particles on the straight line a number of straight lines is less than or equal 0.3㎛, the entire line can be seven or more with respect to 72 to 36 below, one of the resin measured by the distance to the surface of the porous magnetic core particles from a surface of the magnetic carrier particles on the straight line characterized in that the thickness is not more than the number of the straight line B, not more than 36 more than 7 with respect to the total line number of 72 or more 1.5㎛ 5.0㎛.
