Abstract
A detecting device for detecting a surface potential of a photosensitive member includes a first electrode adapted to be positioned with a space relative to a surface of the photosensitive member; a second electrode adapted to be positioned relative to the surface of the photosensitive member at the distance from the first electrode away from the surface; a first detecting portion configured to detect induced charge in the first electrode; a second detecting portion configured to detect induced charge in the second electrode; a calculating portion configured to calculate a surface potential of the photosensitive member on the basis of an output of the first detecting portion and an output of the second detecting portion.
