A developer unit for developing a latent image with marking particles is provided. The developer unit includes a housing defining a chamber for storing a supply of marking particles therein. The developer unit also includes an advancing member for advancing the marking particles on a surface thereof from the chamber of the housing in a first direction toward the latent image. The developer unit also includes a first regulating member for charging the marking particles and for regulating the thickness of the layer of marking particles on the surface of the advancing member. The developer unit also includes a second regulating member spaced from the first regulating member. The second regulating member serves to at least one of charge the layer of marking particles on the surface of the advancing member and regulate the thickness of the layer of marking particles on the surface of the advancing member. The second regulating member is adapted cooperate with the advancing member to charge the marking particles on the surface of the advancing member so as to reduce ghosting when developing the latent image with the marking particles.
