In a developer supply device, a developer carrying portion has a roller main body and a brush layer having flexible fibrous members. A casing includes a developer reservoir portion therein and is formed with an opening portion. The casing rotatably supports the developer carrying portion while the brush layer is exposed externally at the opening portion and opposes a supply target. A developer regulation portion regulates an amount of developer on the brush layer. The developer regulation portion includes a main part and a regulation part. The main part is fixed to the casing, has a plate portion, and extends from one end to another end in an extending direction. The regulation part is connected to the other end. The regulation part enters into the brush layer toward a central rotational axis. A prescribed rotational direction at the regulation part is substantially opposite to the extending direction. |
