ABSTRACT:
A developing method and apparatus of the present invention develops a latent image formed on an image carrier with a two-ingredient type developer, which consists of toner grain and carrier grains, deposited on a developer carrier in the form of a brush. A distance L between a zero field point at which the magnetic field of a main magnet is zero and the image carrier is 4 mm or smaller.
