ABSTRACT:
An electrostatic copying apparatus is provided wherein a stationary original document image is projected onto a photosensitive member during movement of an optical device for exposure. An electrostatic latent image formed on the photosensitive member is transferred onto a copy sheet and is fixed. A jam detecting means is provided for immediately detecting a copy sheet being jammed along a transport path. A cleaning device removes residual toner particles remaining on the photosensitive member by means of magnetic force and stores the removed toner particles after a transferring operation. The occurrence of a jam is detected immediately, and thus a fault or an accident of the electrostatic copying apparatus due to the jam is prevented from continuing.
