Abstract
The invention provides a multi-layered transfer belt for image forming apparatus including a base layer, an elastic layer (intermediate layer) and a surface layer, having a high surface resistivity, an excellent toner releasing property and an excellent non-contaminating property. The transfer belt for image forming apparatus is characterized in including, on the base layer, an elastic layer containing an elastomer and a surface layer formed by a fluorine-containing polymer, and preferably further characterized in that the elastic layer is formed by an elastomer rendered ionic conductive, or in that a binder layer is included between the elastic layer and the surface layer, and that the binder layer is formed by a material having a melting point equal to or lower than a thermal decomposition point of the material constituting the elastic layer and a thermal decomposition point equal to or higher than a melting point of the material constituting the surface layer.
