    Abstract: A heat generating member includes: a hollow cylindrical part that is rotatable about a rotation axis and extends in an axial direction; a first heat generating component provided on an inner surface of the cylindrical part and configured to generate heat when energized; a first connecting component provided on an inner side relative to the cylindrical part and electrically connected to the first heat generating component, the first connecting component being rotatable together with the cylindrical part; a second connecting component provided on a further inner side relative to the cylindrical part than the first connecting component and electrically connected to a power source, the second connecting component being rotatable relative to the cylindrical part; a rotary supporting component that electrically connects the first connecting component and the second connecting component to each other and supports the first connecting component while allowing the first connecting component to rotate relative to the second connecting component; and a second heat generating component provided on a further inner side relative to the cylindrical part than the second connecting component and extending through the cylindrical part in a longitudinal direction of the cylindrical part, the second heat generating component being configured to generate heat when energized, the second heat generating component having a heat generating area different from a heat generating area of the first heat generating component.

    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 pair of decurling units configured to correct curl of a recording medium by sandwiching the recording medium; a switching unit configured to switch the pair of decurling units between a first state in which a pressure contact force is relatively large and a second state in which the pressure contact force is smaller than that in the first state; a release unit configured to release a pressure contact between the pair of decurling units; and a restricting unit configured to restrict release of the pressure contact between the pair of decurling units when the pair of decurling units are in the first state.

    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.
