Image forming apparatus, monocolor image forming apparatus, toner recycling apparatus and intermediate transfer member

摘要

Monocolor image forming unit includes a developing device and an image carrier cleaning device arranged around an image carrier. A plurality of such the monocolor image forming unit is arrayed laterally along the rotary transport direction of an intermediate transfer member of the belt type to configure a tandem image forming device. In the tandem image forming device, a synthesized toner image is formed on the intermediate transfer member and transferred to a recording medium to form a multicolor image thereon. Among the plurality of monocolor image forming unit contained in the tandem image forming device, at least two monocolor image forming unit each include a toner recycling device for conveying toner collected at the image carrier cleaning device to the developing device.
