Developing device with shutter |
摘要 |
A developing device for an electrophotographic copier includes a shutter along its toner supply route and a toner concentration detector sensor connected to a timing circuit. If the toner concentration is detected low, the timing circuit causes the toner supply to continue even after development is completed and the shutter is closed. An auxiliary stirrer is provided to keep stirring freshly supplied toner even after development is completed and the shutter is closed.
