Abstract
An improved magnetic brush developing method for use in electrography which employs a dual-component developing material including electrically insulative magnetizable particles and electrically insulative non-magnetizable particles. In the developing method, magnetic attractive force exerted on the magnetizable particles located at the developing position where a magnetic brush of the developing material formed on a developing material support member is in rubbing contact with electrostatic latent images on a recording medium, is made larger than the electric repelling force acting on the magnetizable particles for preventing the magnetizable particles from adhering to the recording medium.
