transmission of driving force when M29 rotates in the normal direction is limited only to the fixing roller /U
and the fixing paper exit roller.
The same shaft of the one-way clutch [4] is provided with another one-way clutch [5] which is a transmis-
sion to the pressure/release drive cam mechanism [6]. The one-way clutches [4] and [5] operate one way
in the opposite direction of each other.
