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.
