Abstract

PURPOSE: To obtain an electrophotographic developer having a long life and low electric resistance and capable of forming an image free from an internal aperture by blending an electrically conductive one-component type magnetic toner into a spherical carrier and a toner.
CONSTITUTION: Spherical carrier 1, toner 2 and electrically conductive one-component type magnetic toner 3 are blended to obtain a developer. When this developer is carried with a magnetic roll and used in development, an electric current flows from carrier 1 to another carrier 1 through magnetic toner 3, so the electric resistance value of the developer is lowered to enable development free from an internal aperture.
