PURPOSE:To provide a toner replenishing device capable of automatically securing/replenishing spare toner without scattering toner outside a device and interrupting a developing action. CONSTITUTION:The rubbing orbit of the toner in the toner hopper 10 of a toner replenishing member 32 is ordinarily placed on a rotational orbit smaller than the inner diameter of the toner hopper 10, a specific amount of spare toner Ta is secured in the toner hopper 10, and when residual toner reaches a toner end level, the rubbing orbit of the toner in the toner hopper 10 of the toner replenishing member 32 is made higher level by an orbit varying means to automatically replenish the spare toner secured in the toner hopper 10. |
