Abstract:
1. A developer container attachably/detachably mounted in an image forming apparatus, comprising: a container main body formed into a cylindrical shape to store developer used for image formation, the container main body having a concavity, depressed inwardly in a radial direction thereof, to form a storage space on an outer periphery portion of the container main body, and a discharge hole for discharging the developer to the storage space, the container main body conveying the stored developer toward the discharge hole by rotating about an axial line thereof; a supporting member that supports the container main body so that the container main body is rotatable about the axial line by covering a part of the container main body including at least the concavity and the discharge hole over circumferences of the container main body from outside in the radial direction, the supporting member being provided with a leading through hole that is formed so as to face a moving path of the concavity which is formed when the container main body rotates, and that leads the developer discharged from the discharge hole of the container main body to the outside; a developer guiding member that is formed like a sheet, extends upstream in a rotation direction from the leading through hole, and guides the developer discharged from the discharge hole of the container main body to the leading through hole; a deformation preventing member arranged to prevent a plastic deformation of a middle portion of the developer guiding member; and an adhesion eliminating portion for eliminating developer adhering to the developer guiding member, through rotation of the container main body, wherein the adhesion eliminating portion comprises a plurality of concavities, apart from the concavity forming the storage space, forming a corresponding plurality of depressed portions.
