とする磁気ブラシ現像装置。 A magnetic brush composed of toner and a magnetic carrier is formed on a developing roller consisting of a cylindrical sleeve and a magnetic roller disposed inside the sleeve, and a latent image is rotatably provided opposite to this developing roller. In a magnetic brush developing device that develops an electrostatic latent image on a carrier by rubbing it with the magnetic brush through an opening in a device housing, an end portion of the opening in the rotating direction of the latent image carrier is provided. A sealing member made of a magnetic material and magnetized by the magnetic roller is provided, and the sealing member attracts and removes the magnetic carrier transferred to the latent image carrier, and the magnetic carrier is transferred to the magnetic brush. A magnetic brush developing device characterized in that the magnetic brush is collected in a device housing.
