Abstract:
1. An exposure apparatus comprising: a photosensitive member configured to be driven so as to rotate; a charging unit configured to charge the photosensitive member; a light source configured to emit a light beam exposing the photosensitive member; a deflection unit configured to deflect the light beam such that the light beam scans the photosensitive member; a developing unit configured to develop an electrostatic latent image which is formed on the photosensitive member by exposure with the light beam, wherein the light beam emitted from the light source and deflected by the deflection unit exposes the photosensitive member at an exposure position between the charging unit and the developing unit in a rotation direction of the photosensitive member; and a control unit configured to execute a first exposure operation which causes the light source to emit the light beam for exposing the photosensitive member by supplying the light source with a current based on image information, and to execute a second exposure operation which causes the light source to emit the light beam for exposing the photosensitive member by supplying the light source with a current whose value is based on correction data in accordance with a scanning position of the light beam on a surface of the photosensitive member.
