    • An optical scanner includes a rotation control unit to change a number of revolutions of a rotary deflector to change a ratio of a scan speed of a light beam scanned on the surface of a latent image bearing member to a linear velocity of the latent image bearing member in accordance with a change in a linear velocity of the latent image bearing member, an inclination adjustment unit to adjust inclination of a scan line relative to a reference scan line on the latent image bearing member, an inclination adjustment unit controller to adjust the inclination adjustment unit based on the ratio, and a scan initiation unit to initiate scanning of the light beam on the surface of the latent image bearing member after adjustment of inclination is completed and the rotary deflector starts rotating at a constant speed for writing a latent image.
    • 光学扫描器包括:旋转控制单元,用于改变旋转偏转器的转数以改变在潜像承载部件的表面上扫描的光束的扫描速度与潜像承载部件的线速度之比 根据潜像承载部件的线速度的变化,倾斜调节单元,用于调整扫描线相对于潜像承载部件上的参考扫描线的倾斜度;倾斜调节单元控制器,用于调整倾斜调节 基于该比率的单位,并且完成了在调整倾斜之后开始对潜像承载构件的表面上的光束进行扫描的扫描启动单元,并且旋转偏转器以恒定速度开始旋转以写入潜像。
