摘要

A curl correction apparatus includes a supporting member. The supporting member supports a shaft of an elastic roller and a shaft of a metal roller at a first position, and supports only one of the shaft of the elastic roller and the shaft of the metal roller at a second position. When the supporting member is located at the second position, the nip between the elastic roller and the metal roller can be opened by moving the other of the elastic roller and the metal roller.
