ABSTRACT:
A developing apparatus for developing an electrostatic latent image on an image retainer with two-component developer has a rotatable sleeve having a closest position on which the sleeve comes closest to the image retainer, a first magnet fixed in the sleeve in close proximity to the closest position, a second magnet disposed upstream of the first magnet in relation to a rotation direction of the sleeve and a control electrode member. The control electrode member includes an insulating plate member arranged either to be brought into contact with or to be positioned adjacent to the sleeve and a line-shaped electrode member fixed to the plate member.
