When feeding copy sheets having a toner image on one side for making a duplex copy, a feed roll mark is created on the second side if the copies are fed with the imaged side down. This mark is caused by the pressure of the feeding device at the contact point and the slipping of the top sheet off the stack, Since the pressure point is station- ary, a dark mark is created at the pressure point by con- stantly rubbing off some of the toner from the bottom face of the copy sheet being fed onto the top of the hext adjacent copy sheet in the stack.
