Abstract
An image developing device capable of forming a magnetic brush of one-component developer on a developer-feeding magnetic brush roller, and bringing said magnetic brush into contact with a developing roller to form a thin layer of the one-component developer thereon. In the mutually facing area between the rollers the magnetic force of the developing roller for transporting the developer is selected smaller than that of the magnetic brush roller for transporting the developer. The magnetic brush roller and the developing roller are rotated in a same direction so that they are moved mutually oppositely at the mutually facing area thereof.
