Abstract
A transfer type electrophotographic copying apparatus for high speed copying system which includes a photoconductive photoreceptor in the form of an endless belt and movably suspended by a plurality of rollers so as to provide a plurality of flat surfaces. A flat portion which is formed on the photoreceptor belt facing a transfer corona charger and which is directed approximately parallel to a path of a copy paper sheet is effective for shortening the length of the paper path and for improving transferred images, while blower means disposed in a fixing device is adapted to assist in the separation of the copied paper from the photoreceptor belt in normal copying operation, and to direct cooling air to the fixing device in case of paper jamming. Heat shielding means is disposed between the fixing device and the photoreceptor belt.
