An electrophotographic image forming apparatus comprising:
- a main body comprising a connection portion;
- and
- a developing device configured to be attached to and detached from the main body, the developing device including:
- a memory unit configured to provide information about the developing device to the main body, and
- a contact portion configured to be connected to the main body for connecting the memory unit to the main body;
- wherein:
- the connection portion is configured to be connected to the contact portion when the developing device is attached to the main body, and
- one of the connection portion and the contact portion is configured to be positioned at:
- a first location while the connection portion is not connected to contact portion, where the one of the connection portion and the contact portion is inclined with respect to an attaching direction of the developing device to the main body, and
- a second location while the connection portion is connected to the contact portion and the contact portion is connected to the main body for connecting the memory unit to the main body, where the one of the connection portion and the contact portion is in parallel with the attaching direction.
A developing device configured to be attached to and detached from a main body of an image forming apparatus, the developing device including:
- a memory unit configured to provide information about the developing device to the main body, and
- a contact portion configured to be connected to the main body for connecting the memory unit to the main body,
- wherein the contact portion is configured to be positioned at:
- a first location while the contact portion is not connected to the main body, where the contact portion is inclined with respect to an attaching direction of the developing device, and
- a second location while the contact portion is connected to the main body for connecting the memory unit to the main body, where the contact portion is in parallel with the attaching direction.
An electrophotographic image forming apparatus comprising:
- a main body comprising:
- an intermediate transfer belt, and
- a connection portion;
- and
- a developing device configured to be attached to and detached from the main body and to be moved along an attaching path to be attached to the main body, the developing device including:
- a photosensitive drum,
- a memory unit configured to provide information about the developing device to the main body, and
- a contact portion configured to be connected to the main body for connecting the memory unit to the main body;
- wherein:
- the connection portion is configured to be connected to the contact portion when the developing device is attached to the main body,
- the attaching path of the developing device includes:
- a first path in which the developing device is slid in a first direction while the photosensitive drum is separated from the intermediate transfer belt, and
- a second path in which the developing device is moved in a second direction that is perpendicular to the first direction to approach the intermediate transfer belt so that the photosensitive drum contacts the intermediate transfer belt, and
- one of the connection portion and the contact portion is configured to be positioned at:
- a first location, where the one of the connection portion and the contact portion is inclined with respect to the first direction, and
- a second location, where the one of the connection portion or the contact portion is in parallel with the first direction.
