Patent ID: 7923084

Claim:
An intermediate transfer member for use in an image forming apparatus in which a toner image is formed on a photoreceptor, firstly transferred from the photoreceptor to the intermediate transfer member, and further secondly transferred from the intermediate transfer member to a recording medium, the intermediate transfer member, comprising: an intermediate transfer belt containing a volatile substance in a range of from 10 to 10,000 ppm as an average concentration of an entire belt; wherein the intermediate transfer belt comprises a substrate layer and a surface layer formed on or over the substrate layer and the surface layer includes a resin containing a curable functional group; wherein when the concentration of the volatile substance in the surface layer is C 1 (wt/wt ppm) and the concentration of the volatile substance in the substrate layer is C 2 (wt/wt ppm), the surface layer satisfies the following formula: 10 ≦C 1 /C ≦500; and wherein the surface layer is cured so that the intermediate transfer belt has a hardness of 200 to 350 N/mm 2 as Universal hardness.
