Developer transport device and image forming apparatus

A developer transport device comprising:

• a recovery chamber where a developer from an image holding member after transfer is recovered;
• an accommodation chamber that is disposed under the recovery chamber and accommodates the developer;
• a transport unit that transports the developer into the accommodation chamber by rotation;
• a hollow guiding path that is formed in a hollow shape to connect a discharge port of the recovery chamber and an accommodation port of the accommodation chamber to guide the developer in the recovery chamber into the accommodation chamber;
• and
• a transport assisting member that is disposed inside the hollow guiding path and is deformed and restored by rotation of the transport unit to assist transport of the developer inside the hollow guiding path,
• wherein the transport assisting member includes
• a first part that extends along an inner wall surface of the hollow guiding path from the side of the discharge port of the recovery chamber to a position where the first part is in contact with the transport unit, and
• a second part that is disposed to intersect with a front surface of the first part extending along the inner wall surface of the hollow guiding path and extends from an intermediate position of the first part in a length direction to a position where the second part is in contact with the transport unit.
