Abstract

The present invention concerns an image forming apparatus for forming a toner image on a transfer medium by use of an intermediate transfer belt, and also the intermediate transfer belt itself. The intermediate transfer belt has an elastic layer JIS-A hardness of which is 85.degree. or less and at least one covering layer formed on the elastic layer. A relative permittivity .epsilon. and thickness t (.mu.m) of the at least one covering layer satisfy relations of .epsilon..ltoreq.6 and t.gtoreq..epsilon., and the intermediate transfer belt includes a fiber. The effects of this .epsilon. value and the fiber inside enabled to suppress scattering of toner well.
