ABSTRACT:
A copying machine in which a toner image is transferred from an image retaining member to a recording paper and, after the transfer of said toner image, said recording paper is separated from said image retaining member and ejected to the outside of said machine. When said recording paper is attached to said image retaining member due to a separation failure, a detector of the separation failure produces a detection signal for displacing a recording paper conveying device to open the passage of said recording paper and to separate said recording paper onto said conveying device. Said detector comprises a light-emitting element and a light-receiving element and is disposed in the vicinity of a passage provided specifically for the forcibly separated recording paper, so as to detect only said forcibly separated recording paper.
