[4] ITB Belt for performing primary transfer
[5] Flange The shape is sloped to prevent the rib from being placed over it.
Belt displacement is prevented by ITB displacement correction by the rib guide mechanism.
If the rib is placed over the ITB Tension Roller or the flange, the cycle of the side of the belt
on which the rib is mounted over the roller or the flange becomes faster, and a force acts to
restore it.
