An image forming apparatus including an image bearing member; a developing device forming a toner image; a toner supplying device including a toner container, a toner feeding passage, a pump, in which a first member is moved while rubbing a second member to feed a developer supplement including at least the toner, and a residual toner detector detecting the amount of the developer supplement remaining in the toner container. Even after the toner container achieves a near empty state, image forming operations are continued as long as a predetermined condition is satisfied while changing the pump's condition such that the pump is stopped, the ratio of the pump stopping period to the pump driving period is set to be greater than that before the near-empty detection, or the pump stopping period and the pump driving period are set to be longer than those before the near-empty detection.
