A main object of the present invention is to provide an intermediate transfer belt for image-forming devices and a method for producing the intermediate transfer belt, the intermediate transfer belt having excellent
image transfer to rough paper and resistance to abrasion and being free from problems such as filming, by forming a
surface layer that has excellent resistance to abrasion and in which defects such as pinholes are not likely to occur even when the
surface layer is thinned.An intermediate transfer belt for image-forming devices and a method for producing the same, the intermediate transfer belt comprising at least the following three
layers laminated in the described order: (a) a base layer formed from resin, (b) a rubber-elastic layer formed from a rubber or
elastomer, having a thickness of 200 to 400 μm and (c) a
surface layer formed from resin, having a thickness of 0.5 to 6 μm, wherein the intermediate transfer belt has the following properties: (i) the dynamic ultramicro
hardness (ISO14577-1) measured from the surface layer side is 2.5 to 4.5 N / mm2 at the indentation depth of 2 μm, and 1.0 N / mm2 or less at the indentation depth of 10 μm, and / or (ii) the rubber-elastic layer contains a filler in a proportion of 0.4 to 4.0 vol. %, and the ratio (M1 / M3) of the
mass concentration M1 of the filler in the region from the interface between the surface layer and the rubber-elastic layer toward the base layer to a depth of 20 μm, to the
mass concentration M3 of the filler in the region from 120 μm to 140 μm in depth from the interface between the surface layer and the rubber-elastic layer toward the base layer is 1.3 or higher.
