Claims

[Scope of utility model registration request]

(1) A replenishing developer container in which developer to be replenished to the developing device is stored and having an opening at the bottom, a rotating member disposed near the upper surface level of the developer in the developing device, and the opening. and a developer replenishing roll that is rotatably provided and is located between the rotating member and the rotating member so that it can come into contact with and separate from the rotating member depending on a change in the upper surface level of the developer.

(2) The developer replenishing device according to claim 1, wherein the rotating member is a stirring roll that stirs the developer.
