Patent ID: 8223812

Claim:
An exposure apparatus comprising: a light source including a first emitting portion for emitting a first laser beam and a second emitting portion for emitting a second laser beam to expose a photosensitive member; a beam shaping unit disposed on optical paths of the first and second laser beams and configured to shape the first and second laser beams; a first light receiving element configured to receive a light beam of the first laser beam in an area where a light beam does not pass through the beam shaping unit; a second light receiving element configured to receive a light beam of the second laser beam in an area where a light beam does not pass through the beam shaping unit; and a light amount control unit configured to control a light amount of the first laser beam based on a light reception result of the first light receiving element and to control a light amount of the second laser beam based on a light reception result of the second light receiving element; wherein the first light receiving element and the second light receiving element are disposed at a stage subsequent to the beam shaping unit, and receive light beams of the first and second laser beams in an area where a light beam does not pass through the beam shaping unit.
