ABSTRACT:
An electrophotographic image forming apparatus includes a suction transport unit which is provided in the upper housing portion and which sucks paper on a paper transport path and transports the paper along the paper transport path. The suction transport unit has a paper transport surface on which the paper is transported in a state where the paper is sucked. The apparatus also includes a supporting mechanism which flexibly supports the suction transport unit to an upper housing portion of the apparatus, which is rotatably supported to a lower housing portion thereof. A first group of projections projects downward from the suction transport unit, and a second group of projections project upward from the lower housing portion. When the upper housing portion is closed, the first group of projections come into contact with the second group of projections so that the paper transport surface of the suction transport unit is positioned with respect to the paper transport path by the first and second groups of projections.
