A paper transport device includes a transport mechanism that transports paper to which an image is transferred to a fixing device while sucking the paper and a switching mechanism that switches between suction regions in a width direction of the transport mechanism, which corresponds to a width direction of the paper, according to a size of the paper.

Paper transport device

A fixing device includes a circulating endless belt, a fixing unit that is in contact with the belt to form a fixing nip, a heat source provided on an inner side of the belt or on an inner side of the fixing unit, a pressurizing unit arranged on the inner side of the belt to pressurize the belt against the fixing unit, a sheet interposed between the belt and the pressurizing unit to reduce a sliding resistance, and a restricting unit that restricts movement of the sheet in a direction opposite to a moving direction of the belt at a position near a downstream side of the pressurizing unit in the moving direction of the belt.

Fixing device and image forming apparatus

A fixing device includes a belt member, a fixing member facing an outer peripheral surface of the belt member and forming a fixing nip portion between the belt member, and a separating pad portion disposed inside the belt member, including a pressing surface for pressing the fixing member at downstream of the fixing nip portion in a moving direction of the belt member and separating a recording material from the fixing member. The pressing surface of the separating pad portion curves so as to protrude toward the fixing member as approaching a central portion thereof in a rotation axis direction of the fixing member. An upstream end portion and a downstream end portion of the pressing surface curve so as to protrude toward an upstream side in the moving direction as they approach the central portion in the rotation axis direction.
