A developing unit for an electrophotographic processor is described. The unit includes a frame in which the following elements are supported. A developing roller supplies toner to a photo-sensitive drum so as to develop an electrostatic latent image formed on the surface of the photosensitive drum. A supply roller supplies toner to the developing roller. A conductive seal is attached to the frame and prevents toner from escaping between the developing roller and the frame. The seal is grounded or has a reference voltage applied to it, so as substantially to eliminate any electric charge of the toner remaining on the surface of the developing roller after the electrostatic latent image of the photosensitive drum has been developed. Thus, the ghost phenomenon in which characters or pictures of a previous rotation of the developing roller dimly appear in the next image can be prevented. <IMAGE> |
