ABSTRACT:
An electrophotographic copying machine including a unit consisting of a photoreceptor and a developing device. The unit can be pulled out of or into the copying machine. The developing device has a developer outlet provided at its bottom, and first and second grooves. A developer funnel can be coupled to the first groove to receive the old developer from the developing device. The first groove is also provided for guiding a lid closing the developer outlet. The funnel can also be coupled to the second groove to supply the new developer. In a specific form, the developing device can be shifted from a position close to the photoreceptor to a position separate from the same. The developing device can also be moved with a quadric link chain pivotally supported on the frame of the unit of the photoreceptor and the developing device. Positioning members are provided in the frame for positioning the developing device in both positions.
