ABSTRACT:
A transfer assembly of an electrophotographic printer includes a photoconductor drum, a charger disposed against the photoconductor drum for charging a surface of the photoconductor drum, an exposure unit for exposing the charged photoconductor drum to form an electrostatic latent image thereon, a developer unit disposed against the photoconductor drum for providing adhesion of a toner to the electrostatic latent image to form a toner image, a transfer unit disposed against the photoconductor drum for transferring the toner image to a medium, and a fuser for fixing the transferred toner image on the medium. In such an assembly, a part of the transfer unit, which first touches the medium to which the toner image has been transferred, is provided with a conductive material adapted to provide a gradual discharge of electric charge on the medium.
