摘要:
In the image forming method, a color toner image and a transparent toner image are formed using a first developing device containing a first developer including color toner and carrier, and a second developing device containing a second developer including transparent toner and carrier. At least the second developing device includes a developer bearing member bearing the second developer for developing an electrostatic image; a developer supplying passage supplying the developer to the developer bearing member while feeding the developer in a first direction; and a developer feeding passage 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.
