Abstract
A developer container includes a container body, a supporting member, a leading-out member and a spring member. The container body has a first concavity and a discharge hole. The container body is rotated about its axis to convey developer toward the discharge hole. The supporting member supports the container body rotatably about its axis by covering the part including the first concavity and the discharge hole. The supporting member has a leading through hole for leading developer from discharge hole to outside. The leading-out member extends from the leading through hole on an upstream side in the rotation direction. The leading-out member leads developer from the discharge hole to the leading through hole. The spring member loads the leading-out member with a resilient force that tends to bring its upstream side end in the rotation direction into elastic contact with the outer peripheral surface of the first concavity.
