摘要：
A carrier for a developer developing an electrostatic image is disclosed. The carrier contains magnesium from 2.0 to 25.0 by means of number of atoms by percent in surface portion. According to the invention excellent charge rising properties may be consistently exhibited for extended time periods, and neither toner scattering nor background deposits on images are caused.
