A magnetic carrier contains a resin-filled magnetic core particle and a resin covering layer provided on a surface of the resin-filled magnetic core particle. The resin-filled magnetic core particle is a porous magnetic particle containing a resin in pores thereof. The magnetic carrier has a 50% particle diameter (D50) of 30.0 [mu]m or more and 80.0 [mu]m or less on a volume basis. An electric current flowing through the magnetic carrier at a voltage of 500 V ranges from 8.0 to 50.0 [mu]A. A proportion JR1 of a composition that is made up of the resin in a magnetic carrier portion of a region R1 and a proportion JR2 of the composition in a magnetic carrier portion of a region R2 satisfy the following relationship. The region R1 and the region R2 are illustrated in Figure 1. 1.20 <=JR2/JR1<= 2.00.
