Abstract
In a developing apparatus in electrophotographic machines, the surface of a developer guide facing the surface of a magnetic roller includes a first surface area and a second surface area. The first and second surface areas are curved along the surface of the magnetic roller with a space therebetween, and the second surface area is located downstream of the first surface area. The distance between the first surface area of the developer guide and a portion of the surface of the magnetic roller corresponding to the first surface area is larger than the distance between the second surface area of the developer guide and a portion of the surface of the magnetic roller corresponding to the second surface area. A brush of the developer is formed on the surface of the magnetic roller and touches onto the first surface area of the developer guide.
