Abstract: A belt unit includes: a belt-shaped member being endless; and a support member that supports the belt-shaped member and rotates, the support member having a rotating shaft that tilts in: a tilt direction having a component in a first direction intersecting a bisector of a central angle of a wrapping range where the belt-shaped member is wrapped around the support member and a component in a second direction where the belt-shaped member elongates and contracts; and a direction where extent of shifting of the belt-shaped member to one side in the width direction of the belt-shaped member is reduced.

Abstract: A decurling device includes: a first transporter including a transport roller, the first transporter that sandwiches a transported sheet and transports the transported sheet further downstream; and a second transporter including an endless belt that is in contact with the transport roller. The transport roller has an elasticity that, when the belt is pressed against the transport roller, allows the belt to bite into the transport roller by a bite amount corresponding to a pressing force, the second transporter includes an abutting member disposed inside the belt, the abutting member includes an upstream protrusion, an downstream protrusion, the upstream protrusion and the downstream protrusion being provided at positions away from each other at an upstream portion and a downstream portion in a sheet transport direction.

Abstract: A fixing device includes: a fixing member to be used in fixing an image on a recording medium; a rotatable member pressed against the fixing member while being allowed to rotate, the rotatable member cooperating with the fixing member in such a manner as to form a pressurization part where the recording medium is to be pressurized; and a transmission unit configured to transmit a rotational driving force to the rotatable member. The rotatable member is movable in a toward-and-away direction relative to the fixing member. The toward-and-away direction of the rotatable member is different from a direction in which the driving force transmitted by the transmission unit acts.
