特徴とする乾式現像装置。 a developing sleeve that supports a developer and develops an electrostatic latent image formed on a latent image carrier with the developer;
A magnet roller that is provided inside the developing sleeve and rotates to rotate the supported developer around the developing sleeve by magnetic force, a developer removing member that removes the developer on the developing sleeve after development, and a developer removing member for removing the developer on the developing sleeve after development. A toner replenishing member is provided between the developing sleeve and the toner replenishing member, and the toner replenishing member is vibrated by the rotating magnetic field of the magnet roller. A dry type developing device characterized by being provided with a magnetic member for smoothing and directing the developer that is removed and supplied with toner by a toner replenishing member toward a developing sleeve.
