ABSTRACT:
An electrostatic copying apparatus wherein a stationary original document image is projected onto a photosensitive member during movement of an optical device for exposing, and an electrostatic latent image formed on the photosensitive member is transferred onto a copy sheet and is fixed, comprising (a) a jam detecting means for immediately detecting a copy sheet being jammed on a transport path; and (b) a cleaning device for removing residual toner particles remaining on the photosensitive member by means of magnetic force and for storing the removed toner particles after transferring operation. According to this invention, an occurrence of jam is detected immediately, and thus a fault or an accident of the electrostatic copying apparatus due to jam is prevented from expanding.
