ABSTRACT:
An image forming apparatus having a photoconductive element or similar image carrier, and an intermediate transfer belt or similar intermediate image carrier to which a toner image is transferred from the image carrier. A lubricating oil additive whose major component is zinc stearate is melted and then solidified by cooling to form a flat plate-like agent. The agent is transformed to fine particles and applied to the surface of the intermediate transfer belt to eliminate toner filming on the belt. The agent also serves to enhance the parting ability of the belt surface, thereby insuring efficient image transfer from the belt to a recording medium. The surfaces of the photoconductive element, belt and recording medium are so conditioned as to satisfy a predetermined relation with respect to the coefficient of friction.
