摘要： An image-forming device includes a conveying part, an image-forming part, first through third sensors, and a control part. The conveying part is configured and arranged to convey a continuous recording material. The image-forming part is configured and arranged to form an image on the recording material conveyed by the conveying part. The first through third sensors are configured and arranged to detect positions of an edge surface of the recording material conveyed by the conveying part. The control part is configured to calculate first through third shifting amounts based on the positions of the edge surface of the recording material simultaneously detected by the first through third sensors, respectively. The first shifting amount is generated by movement of the recording material, the second shifting amount is generated by rotation of the recording material, and the third shifting amount is generated by fluctuations in the edge surface of the recording material.

摘要： An optical scanning device 65 is adapted to bring a deflector mirror plane 651 into independent pivotal motions about a first axis and a second axis perpendicular to each other. A mirror driver section including a first axis driver and a second axis driver is so controlled as to bring the deflector mirror plane 651 into pivotal motion about the first axis thereby deflecting a light beam L for scanning along a main scan direction. On the other hand, the deflector mirror plane 651 is pivotally moved about the second axis thereby to adjust the scanned beam L for its position on a photosensitive member 2 with respect to a subscan direction. Thus, even if the scanned beam is deviated from a reference scan position with respect to the subscan direction due to component tolerances or assembly errors, such a deviation can be corrected.
摘要翻译：光学扫描装置65适于使偏转镜面651围绕彼此垂直的第一轴线和第二轴线相互独立的枢转运动。控制包括第一轴驱动器和第二轴驱动器的镜驱动器部分，以使偏转镜面651围绕第一轴线枢转运动，从而沿着主扫描方向偏转用于扫描的光束L. 另一方面，偏转器镜面651围绕第二轴线枢转运动，从而相对于副扫描方向调整扫描光束L在感光元件2上的位置。因此，即使由于部件公差或组装误差而使扫描光束相对于副扫描方向偏离参考扫描位置，也可以校正这种偏差。

摘要： An image forming apparatus, includes: a latent image carrier whose surface includes an effective image region spanning across a predetermined width in a main scanning direction and is driven in a sub scanning direction approximately orthogonal to the main scanning direction; a latent image former which has a light source and a deflection mirror oscillating, and deflects a light beam from the light source using the deflection mirror so as to scan the effective image region with the deflected light beam; and a scanning mode controller which switches selectively between a single-side scanning mode and a double-side scanning mode, the single-side scanning mode being a mode in which the light beam is scanned only in a first direction included in the main scanning direction, the double-side scanning mode being a mode in which the light beam is scanned in both the first direction and a second direction opposite to the first direction, wherein a condition to form latent images on the latent image carrier in the single-side scanning mode is different from a condition to form latent images on the latent image carrier in the double-side scanning mode.
