Abstract
A developer container may include a container body accommodating developer, a conveyance member, and a rotation member having a rotary shaft and an elastic part supported by the rotation member and configured to convey the developer. The container body may include a first support part to which the rotary shaft is loosely fitted, and a second support part that supports the rotary shaft. The container body may further include a sliding contact part that the elastic part sliding-contacts while being elastically deformed when the conveyance member is being rotated. In some examples, a distance from a center of the rotary shaft to a leading end of the elastic part gradually increases from the one end portion-side of the rotary shaft towards the other end portion-side of the rotary shaft.
