ABSTRACT:
An electrophotographic copying apparatus has increased speed in recording sheet conveyance where the conveying path from the sheet feed cassette to the photosensitive member is relatively long. The sheet conveyance apparatus is constructed to equalize the line speed of the photosensitive member, the feed speed of the recording sheet and the conveying speed of the recording sheet. A plurality of sheets serially fed out from a sheet tray are concurrently transported along the sheet path. A sheet is fed out from the sheet tray in response to a timing reference signal generated in response to the scanning operation for a previously fed out sheet.
