摘要： It is an object of the present invention to provide an optical multi-beam scanning device and an image forming apparatus which adopt a horizontal synchronization sensor and can suppress displacement in a horizontal scanning direction even when latent images are written on a surface to be scanned by a plurality off light beams tilting with respect to the surface to be scanned. In the optical multi-beam scanning device of the present invention, when the light beams are assumed to reach the surface to be scanned with the light beams not being folded, the horizontal synchronization sensor is tilted so as to output a horizontal synchronized signal when the light beams come to the same position on the surface to be scanned in the horizontal scanning direction. In another method, the horizontal synchronization sensor is not tilted, and the similar function is executed by setting a boundary position between a shielding portion and a non-shielding portion of a light shielding member provided on an upper stream side. The image forming apparatus of the present invention adopts the optical multi-beam scanning device of the present invention.

摘要： An optical beam scanning device includes a rotating polygon mirror for scanning a beam from a pre-deflection optical system in a main scanning direction and two mirrors 23, 25 for imaging the beam scanned by the rotating polygon mirror 5 on an image plane. The device is arranged so that a first mirror 23 at the rotating polygon mirror side 5 has a negative power in the main scanning direction and a second mirror 25 at the image plane side has a positive power in the main scanning direction. Thereby, the degrees of freedom of shape and arrangement of process unit or the like can be made higher and an apparatus can be downsized by securing the distance between the last imaging element and the image plane while suppressing the increase in the optical path length between the reflection surface 5A of the rotating polygon mirror 5 and the image plane.
