Abstract
PURPOSE:To measure the characteristic of each type of electrostatic charger by means of an image forming device itself by detecting an electric current flowing from an image carrier according to the action of an electrostatically charging means by means of a detecting means and obtaining an electrical potential on the surface of the image carrier in response to the electric current by means of a control means. CONSTITUTION:With a control part set in a measuring mode, electrical charges are projected on the surface of a photosensitive body drum 11 by moving the required electrostatic charger and a leaking electric current is detected which is caused by projecting the electrical charges to a destaticizing body. The electrical potential, etc., on the surface of the photosensitive body drum 11 corresponding to the leaking electric current are displayed on the display part 17c of an operation panel 17. Therefore, when the electrical potential, etc., on the surface of the photosensitive body drum 11 are measured, it becomes unnecessary to replace the photosensitive body drum with a jig or to connect a different type of ammeter. Thus, the image forming device itself can perform measuring and a measuring work can be simplified.
