A magnetic carrier for a developer used in electrostatically forming a visual image, comprising a magnetic core material, an electrically-conductive particle-containing resin layer and electrically-conductive particles externally added to the electrically-conductive particle-containing resin layer, the magnetic carrier having a magnetization ( sigma 1000) of 61-100 emu/g at 1 kOe magnetic field, a specific volume resistance of 106 OMEGA xcm or less, and an average particle size of 10-100 mu m. The magnetic carrier of low specific volume resistance has a high durability and provides high quality images. In particular, when the magnetic carrier is applied to an image forming process by rear side exposure, the residual toner on the image-bearing member can be effectively removed without using an additional cleaning means, and high quality images free from the background fogging and contamination can be produced.
