Claim 0:
1. An intermediate transfer belt cleaning system comprising:
an intermediate transfer belt that has an outer peripheral surface to which a toner image is to be transferred; and
a cleaning device having a cleaning blade that comes into contact with the outer peripheral surface of the intermediate transfer belt to clean the outer peripheral surface,
wherein the cleaning blade has a peak value (tan δp) of a loss tangent of 0.25 or more and 0.40 or less at a frequency of 1 Hz and a loss tangent (tan δ22) of 0.20 or more and 0.35 or less at 22° C. at a frequency of 1 Hz, the tan δp and the tan δ22 being determined by measuring temperature dependence of viscoelasticity of the cleaning blade, and
a coefficient D of dynamic friction between the intermediate transfer belt and the cleaning blade is 0.30 or more and 0.80 or less.
