A developing device for developing a latent image formed on an image carrier of the present invention includes a rotatable, nonmagnetic developer carrier, and a magnetic field generating member for generating a magnetic field in a developing zone where the developer carrier faces the image carrier. The magnetic field generated causes a developer deposited on the developer carrier to rise in the form of a magnet brush. A magnetic pole for development is located upstream of a position where the developer carrier and image carrier are closest to each other in a direction of rotation. A magnetic force, as measured on the surface of the developer carrier, increases from the position of the magnetic pole toward a position where the magnet brush finally leaves the image carrier.
