Abstract
A transfer belt is configured to transfer a toner image carried on a first main surface of the transfer belt to a recording medium. When the transfer belt is pressed with pressure application three increased at a predetermined pressure application rate and is then pressed with certain pressure application force by using a lower block provided with a hole and an upper block, k2 [μm/s] satisfies 6≤k2≤30, k2 [μm/s] being determined by (a−b)/{2×(t2−t1)}, where a [μm/s] represents a maximum value of a displacement amount of a measurement region that is a portion of the first main surface corresponding to the hole, b [μm] represents a convergence value thereof, t1 [s] represents a time when the maximum value is observed, and t2 [s] represents a time when the displacement amount reaches (a+b)/2 again after the maximum value is observed.
