A developer container includes a container main body, a supporting member (32) and an information storage portion (100). The container main body is formed in a cylindrical shape and contains therein the developer for use in image formation. The supporting member (32) supports the container main body (31) rotatably about an axis (L31). The information storage portion (100) is fixed to the supporting member (32) and stores developer associated information of the developer contained in the container main body. Guide holes (111) stably guide the supporting member (32) in attachment direction (E1) so that the information storage portion (100) is connected to an information reading portion provided in an image forming apparatus in such a manner that the information reading portion can read out the developer associated information in the state where the developer container is mounted to the image forming apparatus.
