ABSTRACT:
An imaging forming apparatus in which a photosensitive member is electrostatically charged and the charged area is exposed to light to form a latent image which is subsequently developed to obtain an image the apparatus being featured in that the imaging area on the photosensitive member is exposed to the light of an arbitrary amount while the non-imaging area on the photosensitive member is exposed to the light of an amount determined irrespective of the arbitrary amount, and the surface potential of the area exposed to the light of the determined amount is measured thereby controlling the image formation according to the measured output.
