ABSTRACT:
A paper transporting device for an image recorder for transporting, after a visible image formed on the surface of an image carrier by an electrophotographic procedure has been transferred to a paper sheet by an image transferring device, the paper sheet separated from the image carrier to a fixing device by orienting one surface of the paper sheet carrying the visible image downward and by sucking the other surface by a suction source. A guide member has a transport surface for transporting the paper sheet while guiding it. A number of holes for suction are formed through the transport surface. A plurality of guide ribs protrude from the transport surface. The holes are positioned at opposite sides and in close proximity to the guide ribs. A ground plate covers the entire transport surface and is connected to ground. During transport, the paper sheet slides on and along the edges of the ribs while being spaced apart from the transport surface at opposite sides of the guide ribs. The holes of the transport surface are so positioned as to align with the spaced portions of the paper sheet and, so long as the paper sheet has ordinary elasticity, they are prevented from being stopped up by the paper sheet.
