Intermediate Transfer Unit With Selectable Resistive Elements

The power supply line for each primary transfer member is segmented into multiple resistive elements (first, second, third resistive elements) with different resistance values. This segmentation allows selective connection of specific resistive elements to precisely control the current value flowing through each primary transfer member, thereby resolving the contradiction between control precision and structural simplicity.

Different resistive elements are connected to different primary transfer members based on their specific current requirements. Each primary transfer member can be equipped with a tailored combination of resistive elements (e.g., some members use only the first resistive element, others use first and second, etc.), allowing localized optimization of current control for each transfer member while maintaining overall system manageability.

The power supply configuration applies local quality by providing different resistive element combinations to different primary transfer members based on their individual performance characteristics. This allows each transfer member to receive optimized current control tailored to its specific needs, ensuring consistent transfer performance across all members while avoiding the need for complex centralized control mechanisms.

The resistance values of the resistive elements are specifically designed to compensate for variations in electrical characteristics among different primary transfer members. By changing the resistance parameters (first, second, third resistive elements with different values), the system achieves uniform current distribution and consistent transfer performance despite inherent differences in the transfer members' electrical properties.
