ABSTRACT:
A method for measuring an electrostatic potential, in an electrophotographic type image forming apparatus to form an image using a photosensitive drum. An electrostatic potential measuring device is provided opposedly to the surface of the photosensitive drum, and at a position away from a position to which devices such as a charger are opposed, and the photosensitive drum is rotated, immediately after the photosensitive drum stops and the devices such as a charger is turned on for a fixed period of time, and at the same time, the measurement of an electrostatic potential of the surface of the photosensitive drum by the electrostatic potential measuring means is started.
