ABSTRACT:
There is provided a process for developing electrostatic latent images comprising using a dry magnetic developer comprising an insulating toner and magnetic carriers, said magnetic carriers comprising a ferromagnetic carrier composed of a ferromagnetic material and a binder-type magnetic carrier, said ferromagnetic carrier being composed of resin-coated or bare particles of a ferromagnetic material, said binder-type magnetic carrier being composed of particles of a powdered magnetic material dispersed in a resin binder and having a coercive force greater than that of the ferromagnetic carrier.
