    • An image forming apparatus includes a transport mechanism transporting a recording medium on a belt which is transported at a constant speed in a transport direction, a plurality of electrostatic recording units arranged in the transport direction of the recording medium and transferring toner images of different colors, a positional error detecting part using the toner image of a reference color transferred by one of the electrostatic recording units as a reference image, and relatively detecting positional error information related to positional errors of the toner images of remaining colors transferred by the remaining electrostatic recording units with respect to the reference image, and a positional error correcting part relatively correcting the positional errors of the toner images transferred by the remaining electrostatic recording units based on the positional error information. The positional error detecting part includes a part for controlling the electrostatic recording units to transfer at least two resist marks on the belt at a scan starting end and a scan terminating end of the belt in a main scan direction which is perpendicular to the transport direction of the recording medium, with respect to each of the colors, and a second part, including a sensor detecting the resist marks, for detecting positional error quantities of the resist marks of each of the remaining colors with respect to the resist marks of the reference color based on detection times of the resist marks of reference color and the remaining colors.
    • 图像形成装置包括:传送机构,其将输送方向上以恒定速度输送的传送带传送到记录介质;多个静电记录单元,沿着记录介质的输送方向排列,并且转印不同颜色的调色剂图像; 使用由静电记录单元之一转印的参考颜色的调色剂图像作为参考图像的位置误差检测部分,以及与由剩余静电记录单元传送的剩余颜色的调色剂图像的位置误差有关的相对检测的位置误差信息 以及基于位置误差信息相对校正由剩余静电记录单元传送的调色剂图像的位置误差的位置误差校正部分。 位置误差检测部分包括用于控制静电记录单元的部分,以在扫描起始端和带的扫描终止端沿主扫描方向传送至少两个抗蚀剂标记,该主扫描方向垂直于传送方向 所述记录介质相对于每种颜色,以及第二部分,包括检测抗蚀剂标记的传感器,用于检测每个剩余颜色的抗蚀剂标记相对于参考颜色的抗蚀剂标记的位置误差量 基于参考颜色的抗蚀剂标记的检测时间和剩余的颜色。
