ABSTRACT:
An electrophotographic copying apparatus includes a photosensitive surface capable of retaining an electrostatic latent image for at least two cycles of the surface so a first copy of an original can be made upon scanning the original and the latent image can be recycled to produce a second copy of the same original during the return of the scanning mechanism. The apparatus includes an improved mechanism for driving the scanning mechanism, as well as improved developing and transfer stations.
