    • An image forming apparatus includes a plurality of image carriers, a drive mechanism, a plurality of drive force transmission gears, a phase difference detector, and a shift unit. The plurality of image carriers forms images of separate colors. The drive mechanism including a single drive unit for driving the plurality of image carriers simultaneously. The plurality of drive force transmission gears, provided for each of the image carriers, transmits a driving force from the drive unit to the image carriers. The phase difference detector detects a phase difference in drive speed among the image carriers. The shift unit, provided for each of the plurality of drive force transmission gears, meshes or unmeshes the drive force transmission gear to the drive mechanism. The shift unit is activated to correct any phase difference in drive speed of the image carriers based on a detection result detected with the phase difference detector.
    • 图像形成装置包括多个图像载体,驱动机构,多个驱动力传递齿轮,相位差检测器和移位单元。 多个图像载体形成单独颜色的图像。 驱动机构包括用于同时驱动多个图像载体的单个驱动单元。 为每个图像载体设置的多个驱动力传递齿轮将驱动力从驱动单元传递到图像载体。 相位差检测器检测图像载体之间的驱动速度的相位差。 为多个驱动力传递齿轮中的每一个设置的换档单元将驱动力传动齿轮啮合或不啮合到驱动机构。 基于用相位差检测器检测的检测结果,移位单元被激活以校正图像载体的驱动速度的任何相位差。
