Developing device

A developing device mountable on an image forming apparatus, the developing device comprising:

• a main body portion including a developing container configured to accommodate a developer containing toner and a carrier, and a developer carrying member configured to carry and feed the developer to a developing position where an electrostatic image formed on an image bearing member is developed;
• a fixing portion fixed to the image forming apparatus to mount the developing device on the image forming apparatus in a state in which the main body portion is positioned in the image forming apparatus and the fixing portion is positioned in the image forming apparatus;
• a connecting portion configured to connect the main body portion and the fixing portion;
• and
• a developing side electric contact portion provided on the fixing portion and configured to contact a main assembly side electric contact portion of the image forming apparatus in a state in which the main body portion is positioned in the image forming apparatus and the fixing portion is positioned in the image forming apparatus,
• wherein in a case where the developing device is pressed by a pressing portion of the image forming apparatus in a state in which the fixing portion is fixed to the image forming apparatus, the main body portion is rotated about the connecting portion as a rotation center so that the developer carrying member is moved from a separated position separated from the developing position to the developing position.
