DEVELOPER REPLENISHING DEVICE, DEVELOPING DEVICE INCLUDING THE SAME, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To suppress the clogging of a developer (toner) occurring in the vicinity of a discharge port in a path in a developer replenishing device and to prevent image quality defects caused by the clogging of the developer.SOLUTION: The toner stored in a toner storage part 31 is supplied to a first conveyance part 32 by a rotation paddle 35 and then, conveyed to a toner discharge port 33 by a first conveyance member 321. Surplus toner which is not discharged from the toner discharge port 33 flows into a second conveyance part 34 through a first communication part 36. Since the toner is not excessively flocculated in the vicinity of the toner discharge port 33, the clogging of the toner never occurs. On the other hand, the surplus toner flowing into the second conveyance part 34 is conveyed by a second conveyance member 341.
