Abstract: A belt supporting roll configured to support an endless belt while allowing the belt to rotate includes: a roll body around which the belt is to be wrapped; a holding component extending in an axial direction of the roll body and holding two ends of the roll body while allowing the roll body to rotate; and a supporting component provided at a lengthwise central part of the holding component and supporting the roll body and the holding component while being movable. The supporting component has a range of motion containing a first directional component and a second directional component. The first directional component intersects a bisector of a central angle of an angular range by which the belt is to be wrapped around the roll body. The second directional component is parallel to the bisector.

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 device body, a fixing unit, a pair of decurling units, and an open/close unit. The fixing unit is disposed on the device body to perform a fixing operation on a recording medium, and includes a removal assistance unit to assist removal of the recording medium. The pair of decurling units are disposed on the device body to correct a curl of the recording medium by holding the recording medium therebetween. The open/close unit is openably and closeably disposed on the device body to separate, when opened, the removal assistance unit from the fixing unit and one of the decurling units from the other decurling unit.

Abstract: A transport device includes a first transport member that orbits in a predetermined direction and transports a sheet-like medium; a second transport member that forms a first sandwiching region that is curved and a second sandwiching region that is curved in a direction opposite to the first sandwiching region between the first transport member and the second transport member, and sandwiches and transports the medium in the first sandwiching region and the second sandwiching region; and a changing unit that changes a positional relationship between the first transport member and the second transport member so as to increase a width of the other of the first sandwiching region and the second sandwiching region in a transport direction of the medium without increasing a width of one of the first sandwiching region and the second sandwiching region in the transport direction of the medium.
