Abstract

PURPOSE:To maintain the rate of toner always constant with a simple configuration by opening both openings fitted to a toner bottom and the openings of a go and back-moving plate arranged over the bottom openings through a cam board for a short period to replenish toner. CONSTITUTION:Openings 3 and 4 are attached to the bottom 2a of a toner tank 2 over the whole length of width direction, openings 11 and 12 are also attached to a go and back-moving plate 5 and pins 8 and 9 coinciding with long holes 6 and 7 slide front and back through a cam board 15. At the toner replenishing, the openings 11 and 12 are overlapped with the openings 3 and 4 temporarily and these are opened for a short time of 0.1-1sec, to make a toner T easy to drop. When a space is formed on the surface of a developing agent De in this state, toner T drops to be replenish. Since the space corresponds to the comsumed quantity of toner, the rate of toner in the developing agent is maintained constantly by filling the space with new toner.
