ABSTRACT:
An image forming apparatus includes a copying apparatus and a paper re-feeding apparatus. The paper re-feeding apparatus includes a paper guide unit for feeding paper having an image formed by the copying apparatus to the copying apparatus again. The paper guide unit includes an upper guide opposing the upper surface of the paper, and a lower guide opposing the lower surface of the paper. The paper guide unit also has a main frame for supporting the upper guide, and a subframe for supporting the lower guide. The subframe can be pulled out from the main frame. When the subframe is pulled out, the upper and lower guides are separated vertically, thereby widening a convey path for the paper.
