Abstract

The invention provides a developer container and an image forming apparatus. The developer container includes a container body, a rotating member, and a position regulating portion. The rotating member includes both end portions in axial direction rotatably supported by a pair of sidewalls. The position regulating portion is located in the container body so as to cover a part of the rotating member. The rotating member includes a large-diameter portion and a small-diameter portion. The large-diameter portion is formed to have an outer diameter rotatable around a shaft inside the position regulating portion. The small-diameter portion is formed to have an outer diameter smaller than the large-diameter portion. The position regulating portion includes a cut-out portion that regulates passingof the large-diameter portion and permits passing of the small-diameter portion. The small-diameter portion is arranged by being displaced in the axial direction from an inside of the position regulating portion, and the large-diameter portion is arranged inside the position regulating portion. According to the developer container and the image forming apparatus, the rotary part is inhibited fromseparating. Additionally, the rotary part is easy to assemble.

Description

technical field [0001] The present invention relates to a developer container containing developer and an image forming apparatus equipped with the same. Background technique [0002] A typical image forming apparatus has a developing device that develops an electrostatic latent image on an image carrier into a toner image. The developer is contained in a developer container, and is supplied from the developer container to the developing device. [0003] A developer circulating agitation device having a spiral roller for conveying toner in a developing container has been proposed. The shaft of the screw roller passes through a partition wall formed in the center of the developing container in the axial direction. Both ends of the shaft are rotatably supported by a pair of side walls of the developing container. The partition wall is provided to divide the toner transport path into left and right. [0004] For example, the developer circulation stirring device (toner cont...
