Abstract
A fixing device for fixing a toner image on the surface of a sheet material within an electrostatic copying machine. A movable supporting member rotatably mounts a follower fixing roller for free movement between a press-contacting position, at which the follower fixing roller is maintained in press-contact with a rotatably mounted driven fixer roller, and an isolated position at which at least the greater portion of the follower fixing roller in its longitudinal direction is isolated from, or maintained out of press contact with, the driven fixer roller. A control mechanism moves the supporting members to the press-contacting position in response to energization of a dirve source to which the driven fixer roller is connected and to the isolated position upon deenergization of the drive source.
