ABSTRACT:
A transfer method for electrophotography uses a two-component developer including a magnetic carrier and a magnetic toner. The toner is transferred to a recording sheet while holding the magnetic carrier on a surface of a developer-holding body with a magnetic member which is capable of magnetic adsorption. The magnetic member is disposed in an interior of, or on an inner surface of, the developer-holding body, at a location corresponding to a location at an outer surface of the developer-holding body past which the recording sheet is fed. Due to the magnetic member, the magnetic carrier is not at all transferred to the recording sheet, and an excellent image can be obtained.
