Abstract
An image forming apparatus of an electrophotographic type including a paper feeding device for separating and feeding piled recording paper, an image forming device for forming the image in order on the fed recording paper, a paper turning-over device for switching back the recording paper and turning over the front and rear tip ends of the recording paper, and a paper re-feeding device for re-feeding the recording paper having the image on one-side surface. In such an apparatus, the both-surfaces image formation can be practiced at the same paper distance, keeping the image forming apparatus small in size and low cost. Furthermore, a conveying roller for switching back the paper and sending out the paper to a printer engine is provided such that the rear tip end of the paper accommodated in the switching-back path becomes the front tip end thereof, and a jogger for performing compensation of lateral registration for the paper is provided in the switch-back path. In a configuration, the paper feeding device is controlled such that the sent-out preceding paper and a next paper just subsequent thereto to be accommodated in the switch-back path are at least partially superposed on eac…
