Abstract:
An image-forming apparatus comprising a toner-supplying roller, a developing roller, a photoconductor and a developing blade that is in contact with the developing roller to form a toner layer on the developing roller,wherein the toner-supplying roller supplies toner to the developing roller, and the developing roller applies the toner to an electrostatic latent image on the photoconductor to form a toner image, thereby the toner image is transferred onto a print medium and finally fused into a permanent image, wherein the toner includes a lubricant that remains solid at room temperature and melts at a fixing temperature, and wherein at least one of the toner-supplying roller and the developing roller is a silicone roller that contains non-cured siloxane that must fall in the range of 10 to 8,000 PPM, so that siloxane on a surface of the silicone roller prevents filming of the lubricant on the developing blade.
