Abstract
A developer container includes: a containing unit that contains developer; a transport unit that transports the developer; and a receiving unit that receives a driving force transmitted from a transmitting unit of a body of an image forming apparatus and transmits the driving force to the transport unit. The developer container is removably attachable to the body of the image forming apparatus. The developer container includes a first rotation stopping portion and a second rotation stopping portion that is farther from the receiving unit than the first rotation stopping portion. When the developer container is attached to the body of the image forming apparatus, the first rotation stopping portion comes into contact with a first rotation stopper portion provided on the body of the image forming apparatus, and the second rotation stopping portion comes into contact with a second rotation stopper portion provided on the body of the image forming apparatus. A spatial allowance between the first rotation stopping portion and the first rotation stopper portion is less than a spatial allowance between the second rotation stopping portion and the second rotation stopper portion.
