摘要： A magnetic brush developing apparatus includes a material transport guide member extending from a developing material supply position to a developing region, in addition to a rotatable developing sleeve having an inwardly disposed rotatable manetic roller driven for rotation in the same direction as the sleeve. A clearance is maintained between the guide member and the outer peripheral surface of the developing sleeve to allow transport by the rotation of the magnetic roller of developing material, having magnetic carrier particles and electrically insulative toner particles, from the developing material supply position along the outer surface of the guide member to the developing region in a direction opposite to the direction of rotation of the magnetic roller and developing sleeve. Part of the used developing material is moved in a direction opposite to the direction of transportation of the supplied developing material through the clearance between the developing sleeve and the guide member by the rotation of the developing sleeve, so that undesirable exchanging between the fresh developing material and the used developing material is substantially prevented by the guide member.
