Abstract

An electrophotographic apparatus in which photosensitive paper travels through a substantially U-shaped path, comprises a base and a frame assembly provided on the base in a freely openable and closeable manner. Those components which require higher accuracy in mutual positioning, such as a paper feeding device, an exposure device, a cathode ray tube, a cathode ray tube optical device, a format and a format optical apparatus, are mounted on the frame assembly, and those components which require less accuracy in mutual positioning, such as a developing device, a motor and the like, are mounted on the base. The respective images from the format and the cathode ray tube are focused on an exposure plane of the exposure device in superimposed relation.
