摘要： In the optical deflector, the mean width of profile elements of a cross section of the deflection surface in the sub scan direction is set to be less than the spacing between spots of the light beams formed in the sub scan direction of the deflection surface. This makes it possible to prevent a variation in the size and shape of the spots of the light beams deflected by the deflection surface due to the undulation (unevenness) of the deflection surface. As a result, it is able to suppress a decrease of the granularity of images and form images with high quality.
摘要翻译： 在光学偏转器中，偏转面的副扫描方向的截面的轮廓元件的平均宽度被设定为小于在偏转面的副扫描方向上形成的光束的光斑之间的间隔。 这使得可以防止由于偏转表面的波动（不均匀）而由偏转表面偏转的光束的斑点的尺寸和形状的变化。 结果，能够抑制图像的粒度的降低，并且以高质量形成图像。
