Abstract:
1. An image forming apparatus comprising: a rotatable photosensitive member; a charging unit configured to charge the photosensitive member; an exposure unit configured to form an electrostatic latent image on the photosensitive member by exposing the charged photosensitive member; a detecting unit configured to detect a current flowing between the charging unit and the photosensitive member; and a correction unit configured to determine a fluctuation location of the charged potential of the photosensitive member according to a fluctuation amount of the current detected by the detecting unit, the fluctuation location being caused by contact between a portion of the charging unit and the photosensitive member, and to correct an amount of light irradiated by the exposure unit onto the photosensitive member at the fluctuation location of the charged potential.
