ABSTRACT:
In an image forming apparatus according to the present invention, the scanning operation of an original can be controlled independently from the pressing transferring operation of an image of an original, so that both the scanning speed and the pressing-transferring speed can be adjusted respectively at the optimum speed. Moreover, the suspension roller for suspending a photoreceptive sheet has a common driving source with the optical system, it is advantageous that no special driving means or no special synchronizing means for the suspension roller is needed, and manufacturing cost can be reduced with a simple easy design.
