装置。 a case member that supports both axial ends of a rotationally driven photoreceptor; a guide frame having one end rotatably attached to the lower end of the case member and the other end removably attached to the case member; and the photoreceptor. A corona discharger has a charge wire elastically stretched thereon and is detachably attached to the guide frame, and a charge wire of the corona discharger on the guide frame is attached to the guide frame by attaching the guide frame to the case member. The charge wire is stretched so that the charge wire portion facing the photoreceptor is parallel to the photoreceptor, and a charge wire is provided on the lower surface of the case body so as to shield the charge wire portions on both outer sides of the parallel charge wire portion and the photoreceptor. A corona discharger mounting device comprising:
