摘要： An image forming apparatus includes a developing-device assembly, developing rollers, roller drive gears, a transmission gear, a roller drive motor, a take-in gear, and a generator. The developing-device assembly rotates and stops at a development position where a developing device faces a photosensitive member, thereby switching a developing device to the next one. At the development position, the developing roller provided on each of the developing devices supplies toner to the photosensitive member, and the roller drive gear attached to each developing roller meshes with the transmission gear. The roller drive motor transmits mechanical power to the transmission gear via a power transmission path. The take-in gear disposed coaxial with a rotational center of the developing-device assembly is meshed with the transmission gear. The generator is housed in the developing-device assembly and has a gear meshing with the take-in gear.

摘要： A tandem image forming device for an image forming apparatus of the present invention includes a plurality of image forming means arranged side by side along an intermediate image transfer belt. The image forming means each include a developing device and a cleaning device arranged around an image carrier. One of nearby image forming means has its cleaning device positioned above the developing device of the other image forming means, e.g., an agitating section forming part of the image forming means. This configuration insures smooth circulation of a developer and therefore obviates an irregular developer distribution while reducing the overall size of the image forming device.
