PROBLEM TO BE SOLVED: To make image quality high by simultaneously preventing adverse influence exerted on recovered toner because toner is triboelectrified and adverse influence exerted on an image because of a foreign matter and flocculated toner in a screw pump and other spots and stably carrying the recovered toner in an image forming device equipped with a toner recycling mechanism using the screw pump. SOLUTION: This image forming device is provided with the toner recycling mechanism 500 for carrying the recovered toner recovered by a cleaning means to a developing device. In the device, the mechanism 500 is equipped with a stirring means 551 selecting and stirring the recovered toner, a powder pump 520, and an air pump for supplying air for fluidizing the recovered toner and carrying it to the pump 520. At least a part of the stirring means is made of conductive material and the stirring means electrifies the recovered toner coming in contact with the stirring means by supplying charge to the stirring means from a charge imparting means 700 connected to the stirring means. |
