Abstract
A developing apparatus for developing a latent image on a latent image bearing member, including a magnetic device for forming a magnetic brush of a developer mixture containing developer particles and magnetic particles; a movable developer carrying member for developing the latent image on the latent image bearing member, the developer carrying member being contactable with the magnetic brush to receive the developer mixture; a magnetic particle blocking member, disposed opposed to the developer carrying member at a position downstream of the position where the developer carrying member is contacted with the magnetic brush, for blocking the magnetic particles to form a coating of the developer particles on a surface of the developer carrying member, wherein the coating of the developer particles is conveyed by the movement of the developer carrying member to a developing station where the latent image is developed with the conveyed developer particles.
