PROBLEM TO BE SOLVED: To achieve stable adjustment of a developer to be supplied when a developer receiving port is disposed on the downstream side in a first conveyance path on a developer conveyance path, in a developing device to which toner is supplied from a toner container in association with a reduction in developer in a developer retaining unit.SOLUTION: A conveyance ability suppressing unit 26 forms a retaining unit 27 at a position opposite to a toner supply port 25. According to the amount of toner in the retaining unit 27, the amount of toner flows into a development housing 210 from a toner container 30 is adjusted. A first paddle 23c passes over a toner from a first conveyance path 221 to a second conveyance path 222. The toner excessively retained in the retaining unit 27 flows out to the second conveyance path 222 side from a gap where the conveyance ability suppressing unit 26 and a first communication path 223 overlap with each other in an axial direction.
