A developing device that suppresses density unevenness, a toner for the developing device, and an image forming apparatus including the same are provided. SOLUTION: A developer carrying member 2, a developer supply means 4, and a developer recovery means 5 are provided, and a section 9 serving as a detour path is stirred between a section 7 of the supply means and a section 8 of the recovery means. While installing the conveying means 6 and depositing the developer in the detour path section, the developer is moved in the order of the supply means section, the developer carrier, and the collection means section in order to replenish the developer. An opening communicating with the replenishing means is provided downstream of the supply path or upstream of the detour path. A developing device 1 set upstream of an opening communicating with a section of a collecting unit, wherein the toner used in the developing device includes a binder resin containing a crystalline resin, and the crystalline resin includes a urethane bond and Contains a crystalline resin having a urea bond Developing apparatus is characterized and.
