ABSTRACT:
An image forming apparatus which includes a paper delivery unit which is provided as to be rockable and displaceable between an operating position close to a photosensitive drum and a standby position remote from the photosensitive drum; a supporting link system, operably coupled to the paper delivery unit, for holding the paper delivery unit at the operating position; and energizing device, operably coupled to the supporting link system, for energizing the paper delivery unit so as to move from the standby position to the operating position. The paper delivery unit includes a transferring device for transferring a toner image from the photosensitive drum onto a sheet, a tractor for feeding the sheet, disposed in the upstream of the transferring device in a paper delivery direction, and a suction feeder for holding and delivering the sheet, disposed in the downstream of the transferring device in the paper delivery direction. A delivery unit frame for supporting the transferring device, the tractor and the suction feeder is pivotally supported by a body frame disposed in the upstream in the paper delivery direction. In other words, the paper delivery unit is held at its operating position by way of the supporting link system, and is moved back to the position from its retracted position by way of the energizing device. The paper delivery unit is thus capable of moving to and from an operating position for, e.g., ease of cleaning the transferring device or removing jammed papers.
