Abstract
An electrophotographic apparatus is disclosed, which has a transfer unit for transferring a toner image formed on a photoconductive drum onto a paper sheet and a manual paper feeding section for manually feeding the paper sheet to the transfer unit. A manually fed paper detector is provided in the proximity of the outlet of the manual paper feeding section. If the manually fed paper detector does not detect any paper continuously for a predetermined period of time from the start of a copying operation, this event is judged to be due to a paper feeding error, whereupon the copying operation is interrupted while the electrophotographic apparatus is restored to a stand-by state.
