ABSTRACT:
Apparatus for separating a sheet of paper to which a developed toner image has been transferred from a moving photoconductive surface by directing a high velocity flow of air against an edge of a leading portion of the sheet on the surface to separate said portion, and exerting pneumatic pressure on the separated sheet portion to separate the remainder of the paper from the photoconductive surface. The high velocity air stream is pulsed to coincide with the arrival of the paper edge at a predetermined point in the separating apparatus.
