发明名称 DEVELOPING CARTRIDGE DEVELOPING DEVICE AND IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To prevent the inside of an image forming device main body from being soiled by splashed toner. SOLUTION: A conductive member 17 is arranged at the downstream side of a developing sleeve 5 in the rotating direction. Since voltage branched from developing bias is applied to the conductive member 17, the toner splashed at a developing time is electrically attached to the conductive member 17, the sleeve 5 or a photosensitive drum 1. Thus, the inside of an image forming device is prevented from being soiled by the splashed toner. It is good that the voltage is applied to the conductive member 17 by utilizing electrostatic capacity constituted by the conductive member 17 and a developer carrier.
