PURPOSE:To prevent the choking of a developer at a reuse duct, by providing a moving member and an impact member which has no driving source to give impact to toner and using a force required for the displacement of the moving member as the driving force of the impact member. CONSTITUTION:A pulley 16 is provided at the lower part of a rotating shaft 15 provided for a developing device 3 and this pulley 16 is rotated with a wire 20. An elastic plate 14 is provided at the upper part of the shaft 15 and an impact member 13 is provided at the tip. A coil spring 18 is provided at one end of the wire 20 and another end is fixed to a pin 25 of a front door 24 of a copy machine main body via a roller 23. When the door 24 is opened, the wire 20 is pulled and gives impact to an external wall of a toner reuse duct 11 with the member 23 via the pulley 16 and the shaft 15 by rotating them. The choking of toner can be prevented by giving impact to the developer in the duct 11. |
