摘要： Prior to the formation of registration pattern images (Step S7), base information is acquired by means of a test pattern sensor detecting a surface of an intermediate transfer belt or particularly a surface of a pattern formation region thereof. A surface condition of the pattern formation region is acquired based on the base information thus acquired, while the formation of the registration pattern images is controlled based on the surface condition. In this manner, the registration pattern images are formed with an adequate consideration given to the surface condition of the pattern formation region where the registration pattern images are to be formed (Step S7). Hence, the positions of the registration pattern images may be detected with high accuracies. As a result, a proper correction of color registration offset may be accomplished, assuredly preventing the occurrence of the color registration offset or degraded color tone.

摘要： The size Hbs of a beam spot of an incident light beam on a deflection mirror surface 651 is larger than the width Hb of the deflection mirror surface 651 when a pivot angle θ is zero, and therefore, Hbs>Hb is satisfied at any pivot angle θ and the deflection mirror surface 651 is overfilled with the incident light beam. Hence, even when beam rotation occurs, only a central portion of the incident light beam is reflected by the deflection mirror surface 651 and guided as a scanning light beam to a scanning lens. Owing to this, the central axis CLs of the outgoing light beam (scanning light beam) Ls from a deflector becomes close to the central axis CLs as it is when the pivot angle θ is zero.
摘要翻译：当偏转镜面651上的入射光束的光束点的大小Hbs比摆动角度θ为零时偏转镜面651的宽度Hb大，因此在任意的转角处满足Hbs> Hb θ和偏转镜表面651用入射光束过满。因此，即使当光束旋转发生时，仅入射光束的中心部分被偏转镜面651反射，并作为扫描光束被引导到扫描透镜。由此，来自偏转器的出射光束（扫描光束）Ls的中心轴线CL随着枢转角度θ为零而变得接近中心轴线CLs。

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.

摘要： A first distance is longer than a second distance. This sets a movable plate 653 apart from the horizontal side portions (first adjacent portions) 652a in the direction Y of a pivot axis, which reduces air resistance against the movable plate 653 and hence the amount of heat generation. A light beam from a first optical system impinges upon a deflection mirror surface 651 from the front side of the deflection mirror surface 651 and along the direction Y of the pivot axis at an acute angle with respect to the surface normal to the deflection mirror surface 651. Hence, the light beam L travels in the space other than the space surrounding the deflection mirror surface 651, namely, the space in the vicinity of a central section of the deflection mirror surface. This realizes scanning with the light beam without thermal influence.
摘要翻译：第一距离长于第二距离。这使得可枢转轴线方向Y上的水平侧部分（第一相邻部分）652a分开的可移动板653减小了对可移动板653的空气阻力并因此降低了发热量。来自第一光学系统的光束从偏转镜表面651的前侧撞击偏转镜表面651，并且相对于垂直于偏转镜表面651的表面以旋转轴线的方向Y照射锐角。因此，光束L在偏转镜面651周围的空间以外的空间，即偏转镜面的中央部附近的空间中行进。这实现了光束的扫描而没有热影响。

摘要： A transmission optical system comprises a concave surface mirror whose reflection surface is directed toward a deflection mirror surface and a transmission lens which is disposed between the concave surface mirror and the deflection mirror surface. A light beam deflected by a deflecting element at a first deflection angle is guided to the concave surface mirror via the transmission lens, and the light beam returned by the concave surface mirror is guided to the deflecting element via the transmission lens. In consequence, the deflecting element reflects the light beam twice, and the light beam is emitted toward a scanning lens at a second deflection angle which is larger than the first deflection angle.

摘要： An optical scanning apparatus in which an exposing signal is generated from pattern data indicating a position to be exposed by a light beam on a surface-to-be-scanned. A corrected exposing signal is generated by varying the width of pulses of the exposing signal in accordance with a distance between an exposing area corresponding to the pulse and an optical axis of the scanning optical system. The light beam is emitted and modulated by the corrected exposing signal. The pulse width and/or the light quantity of the light beam is/are varied in accordance with the distance between the exposing area and the optical axis of the scanning optical system.
