Abstract: A color xerographic printing apparatus exhibiting a very high toner transfer efficiency. A rough-surfaced or bumpy Intermediate Transfer Belt (ITB) provides reduced contact area between toner particles and the ITB. Adhesion forces between the ITB and toner images deposited thereon are minimized thereby reducing the electrostatic forces required for transferring toner images from the ITB to a final imaging substrate or a transfuse belt. The bumpy configuration enables use of small quantities of release agent material such as silicone oil for further enhancing toner image transfer without transfer silicone oil to various components of the apparatus including an imaging member such as a photoreceptor.
