Claims
- 1. An image forming apparatus comprising:a first laser beam and a second laser beam; a deflection unit for deflection scanning the first and second laser beams; a first photosensitive member being exposed by a first laser beam deflection scanned by said deflection unit; a second photosensitive member being disposed at a location more distant from said deflection unit than said first photosensitive member, said second photosensitive member being exposed by a second laser beam deflection scanned by said deflection unit; a first reflection member for reflecting the first laser beam deflection scanned by said deflection unit in a direction away from said first photosensitive member; and a second reflection member for reflecting the first laser beam reflected by said first reflection member in a direction toward said first photosensitive member, wherein the second reflection member is disposed at a position more distant from said first photosensitive member than a path of the second laser beam deflection scanned by said deflection unit; wherein said first reflection member is disposed at a position between the second laser beam deflection scanned by said deflection unit and said first photosensitive member.
- 2. The image forming apparatus according to claim 1, further comprising a third reflection member for reflecting the second laser beam deflection scanned by said deflection unit in a direction toward said second photosensitive member.
- 3. The image forming apparatus according to claim 1, wherein optical paths for the first and second laser beams deflection scanned by said deflection unit extending toward said first and second photosensitive members, respectively, are of equal length.
- 4. The image forming apparatus according to claim 1, wherein said first and second photosensitive members are disposed at a same side with respect to said deflection unit, said apparatus further comprising a third photosensitive member and a fourth photosensitive member disposed at a side opposite to said first and second photosensitive members.
- 5. The image forming apparatus according to claim 4, wherein said deflection unit deflection scans a third laser beam exposing said third photosensitive member and a fourth laser beam exposing said fourth photosensitive member.
- 6. The image forming apparatus according to claim 5, wherein said third photosensitive member is disposed at a position nearer to said deflection unit than a position of said fourth photosensitive member, said apparatus further comprising:a fourth reflection member and a fifth reflection member for reflecting the third laser beam deflection scanned said deflection unit; and a sixth reflection member for reflecting the fourth laser beam deflection scanned said reflection by said deflection unit in a direction toward said fourth photosensitive member.
- 7. The image forming apparatus according to claim 6, wherein said fourth reflection member is disposed at a position nearer to said third photosensitive member than a path of the fourth laser beam deflection scanned said deflection unit, and said fifth reflection member is disposed at a position more remote from said third photosensitive member than a path of the fourth laser beam deflection scanned by said deflection unit.
- 8. The image forming apparatus according to claim 7, wherein optical paths for the first through fourth laser beams extending from said deflection unit to said first through fourth photosensitive members, respectively, are of equal length.
- 9. The image forming apparatus according to claim 1, wherein an angle of a first laser beam incident on said deflection unit is different from an angle of a second laser beam incident on said deflection unit.
