Abstract

An image-forming apparatus includes a toner-supplying roller and a developing roller assembled into a developing unit. The toner-supplying roller supplies toner to the developing roller. The developing roller applies the toner to an electrostatic latent image on a photoconductor to form a toner image. The toner image is transferred onto a print medium at a transfer unit, and finally fused into a permanent image at a fixing unit. The toner includes a wax that remains solid at room temperature and melts at a fixing temperature. At least one of the toner-supplying roller and the developing roller is a silicone roller on which oligomer in the form of siloxane is deposited. The silicone roller contains non-cured siloxane in the range of 10 to 8000 PPM.
