Abstract:
An image forming method comprising the steps of:providing a developer including a toner and a magnetic carrier, a developer carrier configured to convey said developer deposited thereon, and magnetic field generating means fixed within said developer carrier; generating a magnetic field by said magnetic field generating means between an image carrier and said developer carrier in a limited range in which an electric field capable of separating said toner and said magnetic carrier from each other is formed, said limited range being defined by a center angle of said magnetic field generating means ranging between negative 9 degrees to positive 9 degrees; and forming a magnet brush in said magnetic field such that said magnet brush rises, contacts said image carrier, and collapses in the limited range in which the electric field capable of separating said toner and said magnetic carrier from each other is formed, wherein said magnet brush rubs said image carrier to thereby develop a latent image formed on said image carrier.
