摘要： An image forming apparatus includes a plurality of image carriers and an optical writing device including light sources that emit light beams of different wavelengths, a deflector that deflects the light beams emitted from the light sources and synthesized on an identical axis in a sub-scanning direction, a first beam separator, a second beam separator, a first imaging device, and a second imaging device. The first beam separator and the second beam separator are located between the first imaging device and the second imaging device and transmit or reflect the light beams according to travel directions or wavelengths thereof. One of the targets is scanned with the light beam transmitted through the second beam separator. Another target is scanned with the light beam reflected by the second and first beam separators. The first and second imaging devices narrow the beams in the main scanning direction and the sub-scanning direction, respectively.

摘要： A drive transmission device, which is included in an image forming apparatus, includes a drive transmission body to which a drive force is applied from a driving source, and a rotary shaft having a press-in portion mounted on one end thereof in the axial direction. The press-in portion has multiple planes disposed parallel to an axial direction and configured to receive the drive transmission body. The multiple planes include upstream and downstream side planes disposed downstream from the upstream side plane in a press-in direction of the drive transmission body. The upstream and downstream side planes are aligned along the press-in direction of the drive transmission body and have respective distances different from each other from an axial center of the rotary shaft. A distance from the downstream side plane to the axial center is greater than a distance from the upstream side plane to the axial center.
