PURPOSE:To prevent a hand and the periphery of the developing device from being contaminated by providing a discharge hole for a developer to a bottom part and adding a normally closed lid which is energized by a spring. CONSTITUTION:Discharge holes 41 and 42 are formed in the bottoms of conveyance parts 1 and 2 of a casing 7 to overall length and normally closed lids 45 and 46 which are energized by springs are provided to the peripheries of shafts 43 and 44. A recovery box 51 is united along the bottom of the casing 7 by using a coupling pin and a hook. At this time, projections 51e and 51d of the box 51 press only driven pieces 46a and 45a of the lids selectively at the same time to open the lids 45 and 46.
