发明名称 Developing device, image forming method and apparatus, and process cartridge
摘要 <p>In an image forming method, a color toner image and a transparent toner image are formed using a first developing device (4,105A-D) containing a first developer including color toner and carrier, and a second developing device (4,105E) containing a second developer including transparent toner and carrier. At least the second developing device includes a developer bearing member (5,302) bearing the second developer for developing an electrostatic image; a developer supplying passage (9,304P) supplying the developer to the developer bearing member while feeding the developer in a first direction; and a developer feeding passage (7,10,305P) separated from the developer supplying passage at a central portion thereof and feeding the developer used for development in a direction parallel to the first direction The transparent toner includes a resin and a lubricant and has viscoelastic property such that loss tangent has a peak with height of not less than 3 at a temperature of from 80°C to 160°C</p>
