Abstract:
A potential sensor for detecting a surface potential of an electrophotographic photosensitive member includes an insulative film; a thin film electrode layer formed on the film; a curved portion formed by folding back the film so that the thin film electrode layer is inwardly located, the curved potion functioning as a detecting portion for detecting the surface potential of the electrophotographic photosensitive member in contact with the electrophotographic photosensitive member; and an electroconductive shielding portion provided so as to cover an outer surface of the film except for at least an area in which the curved portion is contactable to the electrophotographic photosensitive member, the shielding portion being electrically grounded.
