    • An image forming apparatus maintains a constant beam scanning state so that light beams scan each drum always in the same state once a desired color overlapping accuracy is obtained by controlling color registration in color image formation. This mechanism achieves constantly fine color overlapping without forming a test pattern several times or consuming toner unnecessarily. A beam passage switch is provided in a laser scanning system. Sensors provided near each photosensitive drum determine whether each light beam has scanned a certain portion with no inclination or a certain scanning area, or whether each image magnification provides a desired size. Sensors for detecting scanning light beam obtains the center of light beam in accordance with information on a point at which the sensors start to respond and another point at which they cease responding, for performing several types of control based on the positional information, which provides correct information even though the size or power is different over sevral light beam.
    • 图像形成装置保持恒定的光束扫描状态,使得一旦通过控制彩色图像形成中的颜色配准获得期望的颜色重叠精度,光束将始终处于相同的状态。 这种机制实现了不间断地形成测试图案多次或不必要地消耗调色剂的颜色重叠。 光束通过开关设置在激光扫描系统中。 设置在每个感光鼓附近的传感器确定每个光束是否扫描没有倾斜或某个扫描区域的某个部分,或者每个图像放大是否提供期望的尺寸。 用于检测扫描光束的传感器根据关于传感器开始响应的点的信息和其停止响应的另一个点获得光束中心,用于基于提供正确的位置信息执行几种类型的控制 信息即使大小或功率不同于三光束。
