Abstract
PURPOSE: To perform accurate correction by forming a picture image pattern suitable for measuring the degree of fatigue of a photosensitive body on the photosensitive body in the form of a latent or sensible image, measuring its potential density, contrast, etc., and measuring the actual degree of fatigue of the photosensitive body.
