Abstract
An electrophotographic apparatus wherein a blank is formed at an end of a transfer material to make it easier to separate the transfer material from a photosensitive member and to prevent the transfer material from wrapping around an image fixing roller. A light reflecting portion is formed at a position corresponding to a leading edge of an original on an original supporting platen. The light reflecting portion receives light from an original illuminating lamp and reflects it to the region of the photosensitive member that has been opposed to a charger when the charge is switched from its non-operative state to an operative state.
