The present disclosure discloses print-medium buffering systems that have a set of print-medium-buffer flags (25) which, in one position, maintain a print medium in a guided path (G) as it passes through a print-medium buffer zone. A drive mechanism (30) is provided to move the set of print-medium-buffer flags away from the guided path, to a second position.

A paper feeding unit of an image forming apparatus according to an exemplary embodiment is provided with a base portion, a guide, a protruding portion, and a roller. The base portion is capable of having the sheet placed thereon. The guide erects with respect to the base portion. The guide regulates a position of the sheet in a width direction which intersects with a transporting direction of the sheet. The protruding portion is provided on the guide. The protruding portion faces an end portion of the sheet in the width direction from a side opposite to the base portion. The roller is provided on the protruding portion. The roller is provided with a circumferential surface facing the end portion of the sheet. The roller is rotatable in the transporting direction of the medium.

A sheet conveyer, having a sheet supporting plate, a feed roller, a lifting device to move the sheet supporting plate between a separated position and a contacting position, a motor, a sheet guide disposed on the sheet supporting plate to extend orthogonally to an axial direction of a rotation shaft of the feed roller to be movable in the axial direction on the sheet supporting plate, and a contact member disposed in an upper position with respect to the sheet guide, is provided. The sheet guide includes a retractable member movable between a first position, in which the retractable member is located when the sheet supporting plate is in the separated position, and a second position, in which the retractable member is placed by a reaction force from the contact member produced by contact between the sheet supporting plate and the feed roller.
