  • Method of electrostatic transferring very small dry toner particles using an intermediate
    Patent number: 5370961
    Abstract: A toner particle image made up of toner particles having a mean particle diameter of less than 7 microns and transfer-assisting particles strongly adhering to the surfaces of the toner particles having a mean particle diameter between about 0.01 microns and about 0.2 microns is electrostatically transferred to an intermediate. An intermediate has a base having a Youngs modulus of 10.sup.7 Newtons/m.sup.2 or less and a thin overcoat or skin which has a Youngs modulus of 5.times.10.sup.7 Newtons/m.sup.2 or more. The toner image is then electrostatically transferred from the intermediate image member to a receiving sheet. The surface of the intermediate image member receiving the toner image preferably has a roughness average equal to 20% of the mean diameter of the toner particles or less.
