Tonernachfüllvorrichtung

摘要

A toner replenishing device (30) in accordance with the present invention has a hopper (40) for storing toner. The hopper (40) has an L-shaped so as to have a large volume in a lateral direction, thereby ensuring that the hopper has the volume corresponding to several toner containers (41). The toner stored in a lower portion of the hopper is transported by toner transport devices (48) to the vicinity of a toner supply opening (47) provided on the tip of the hopper. The remaining toner amount detecting sensors (50) detect the amount of toner remaining in the toner replenishing device step-by-step, thereby realizing a toner replenishing device having a large toner storage section (1) in which the aggregation of toner due to the dead weight can be prevented and (2) in which the amount of toner remaining can be displayed step-by-step and the supply of toner can be carried out in advance before the shortage of toner occurs.
