A developer container includes: a first containing portion that contains new developer; a second containing portion that contains developer; a transport unit that transports the developer in the first containing portion toward an outside of the first containing portion; and a receiving unit that receives a driving force from a driving unit of a body of an image forming apparatus and transmits the driving force to the transport unit. The receiving unit is disposed such that a portion of the receiving unit is outwardly exposed at an end surface of one of the first containing portion and the second containing portion in an up-down direction, the exposed portion being in contact with the driving unit.

Developer container and image forming apparatus

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.

A mounting/demounting structure includes: a mountable/demountable object including a body, a first projection provided at a first end of the body in a movable manner, and a second projection provided at a second end of the body in a shiftable manner; and a receptacle including a housing configured to house the object when mounted while covering it in at least two directions, first and second stoppers provided in the housing and configured to stop the first and second projections, respectively by engagement, the object including an abutment portion provided on the body and configured to abut against a part of the housing to keep a posture reduced in terms of an engagement amount between the second projection and the second stopper when the first projection is disengaged from the first stopper and the object is stopped at a tilt in the housing during demounting of the object from the receptacle.
