Abstract
Electrostatographic image reproduction apparatus forms images of toner particles on a receptor material moving along a transport path. A rotatable contact roller contacts the receptor material while it has an electrostatically charged toner particle image on at least the adjacent surface thereof. The contact roller is selected from a receptor material transport roller, a guiding roller, and a reversing roller. Electrostatic charging device provide an electrostatic charge, having the same polarity as the charge polarity of the toner particles, on the surface of the contact roller before contact of the receptor material with the surface of the contact roller. Cleaning means remove any toner particles from the surface of the roller after release of the receptor material from the surface of the contact roller. Smudging of the toner image on the receptor material is reduced.
