Abstract: The present invention is a method of forming a toner image on a receiving sheet. The method includes forming an electrostatic image on a primary image member and toning the image with a dry toner to form a toner image. The toner includes toner particles having a diameter of between 4 and 10 microns and transfer assisting particles appended to the toner particles surface. The transfer assisting particles have a diameter of between 20 and 100 nm. The toner image is transferred from the primary image member to an intermediate image member having an overcoat layer, the overcoat layer having a Young's modulus of from 250 to 500 MPa. The toner image is transferred from the intermediate image member to a receiving sheet wherein the intermediate image member drives the primary image member or the receiving sheet.
