摘要： Assuming the photosensitive drum for black as a reference, the phase of the adjacent photosensitive drum for cyan leads by about 60 deg. Similarly, the phase of the photosensitive drum for magenta leads by about 120 deg., and the phase of the photosensitive drum for yellow leads by about 180 deg. The phase of each photosensitive drum is shifted to thereby make it possible to shift the phase of driving unevenness. By shifting the phase, even the distance between adjoining transfer positions corresponding to the image forming stations is set shorter than the circumference of the photosensitive drum, the variation of each photosensitive drum due to driving unevenness with respect to the printing medium passing through the transfer position can be kept congruent with the others.

摘要： The present invention is intended to reduce a fθ correction error by correcting an error of an object scanning speed which is produced because a reflecting point of a laser beam moves on a polygon mirror (12). In an inventive laser scanner (9), laser light emitted from a laser oscillator (10) is condensed into a beam by a condenser lens (11) at first. This laser beam is reflected by a polygon mirror (12) rotated by a scanning section (13) and is reflected again to a photoreceptor (4) by a curved reflecting mirror (14). A curved profile of a reflecting plane of the curved reflecting mirror (14) in the main scanning direction is formed so as to be asymmetrical on right and left bounding about a scanning center point (14c). Thereby, variation of speed for scanning the curved reflecting mirror (14) by the light reflected by the polygon mirror (12) may be canceled by the curved reflecting mirror (14) and a speed for scanning the object may be fixed almost at a predetermined speed.

摘要翻译：本发明旨在通过校正由于激光束的反射点在多角镜（12）上移动而产生的物体扫描速度的误差来减小fθ校正误差。在本发明的激光扫描仪（9）中，首先从激光振荡器（10）发射的激光通过聚光透镜（11）会聚为光束。该激光束被由扫描部13旋转的多面镜12反射，并通过曲面反射镜14再次反射到感光体4。弯曲反射镜（14）的反射面在主扫描方向上的曲面轮廓形成为在围绕扫描中心点（14c）的左右不对称。因此，由多面镜（12）反射的光扫描弯曲反射镜（14）的速度变化可以通过弯曲反射镜（14）抵消，并且用于扫描物体的速度可以几乎固定在预定的速度。
