    • An automatic developability control system is provided in the developer assembly of an electrostatic reproduction apparatus to sample toner particle developability. Upon an indication that replenishment of toner powder is necessitated, the control system is operative to activate a toner powder dispensing apparatus. The developer mixture may be comprised of magnetic toner particles or magnetic carrier particles to which toner powder is adhered. To prevent debris material such as paper scraps, fibers, dust, bits of rubber, etc. from plugging or jamming the toner powder sensing device of the control system, provision is made for separating the developer mixture from debris material prior to the introduction of developer mixture into the control system.
    • 在静电再生装置的显影剂组件中提供自动显影性控制系统,以对色粉颗粒显影性进行采样。 在指示需要补充调色剂粉末的情况下,控制系统可操作以启动调色剂粉末分配装置。 显影剂混合物可以由附着有调色剂粉末的磁性调色剂颗粒或磁性载体颗粒组成。 为了防止诸如纸屑,纤维,灰尘,橡胶等的碎屑材料堵塞或堵塞控制系统的调色剂粉末感测装置,在引入显影剂之前提供了将显影剂混合物与碎屑材料分离 混合进入控制系统。
