Abstract

PURPOSE:To prevent fresh toner from flowing out without increasing mechanical torque by napping a developer on the back surface side of a toner outflow preventive plate with the repulsive magnetic force between two magnets and extending the tip part of the nap toward the toner outflow preventive plate. CONSTITUTION:The developer 9 which is napped at a part opposing to a 1st magnet 3 and used for development passes between the toner outflow preventive plate 15 and a developing sleeve 2 while not napped as the sleeve 2 rotates and is then napped toward the toner outflow preventive plate 15 with the repulsive magnetic force between a 2nd magnet 4 and a 3rd magnet 5. Consequently, fresh toner is prevented from flowing out without increasing the mechanical torque for driving the sleeve 2.
