PROBLEM TO BE SOLVED: To improve the degree of freedom at a place where a recycled toner transfer device is installed by fixing the toner transfer tube of the recycled toner transfer device to an image forming case for making a cartridge and a developing unit attachable/detachable. SOLUTION: The recycled toner transfer device 21 is provided with the toner transfer tube 27 having an angular cross-section and a toner carrying coil member inserted/provided in the toner transfer tube 27 and fixed so that the tube 27 comes into contact with the front surface part 20A of the image forming case 20. This case 20 is supported to be freely insertible to/removable from an image forming device body 1 by guiding rails 22 and 23 and the cartridge 10 and the developing unit 6 are loaded in the image forming case 20 after being pulled out from above. When a pressure lever 34 provided in the case 20 is pivoted, the developing unit 6 is moved to the side of the cartridge 10, to be set at an image forming position. Therefore, a fault that the recycled toner transfer device 21 is exchanged simultaneously with the exchange of a cleaning device in the cartridge 10 is prevented. |
