Abstract
A copy item transport device is used in an image forming apparatus having an image bearing member and a pair of registration rollers before the image bearing member, and includes a separator for regulating multiple copy items to one copy item for each image formation. The separator is constructed by a forward roller being driven in a forward direction of transporting the copy item to the registration roller pair, a reverse roller in contact with the forward roller. The reverse roller is driven in a reverse direction of transporting the copy item backward, but rotatable in the forward direction together with the forward roller when receiving a greater transmitted forward torque from the forward roller than the reverse torque. The reverse drive to the reverse roller is stopped at the same time or after the forward drive to the forward roller is stopped to assure the nip of copy item by the registration roller pair.
