Developer cartridge, process unit, and image forming device

A process unit that is attached to and detached from an image formation device, the process unit comprising:

• a drum unit supporting at least one of image carrier;
• a power supply member;
• a supporting member;
• and
• a developer cartridge attached to and detached from the drum unit, the developer cartridge including:
• a developer carrier;
• an input gear rotatable about a rotating axis, the input gear communicating with the developer carrier;
• an electrode member that is electrically connected with the developer carrier, the electrode member including a first contact where the electrode member contacts the power supply member;
• and
• a supported member that includes a second contact where the supported member is supported by the supporting member,
• wherein an imaginary plane is defined as orthogonal to the rotating axis of the input gear, the imaginary plane including projections of the input gear, the electrode member, and the supported member, and
• wherein an imaginary line is define as connecting the first contact and the second contact in the imaginary plane, the imaginary line passing through the input gear on the imaginary plane as the input gear is located between the first contact and second contact on the imaginary plane.

An image formation device comprising:

• a body;
• at least one of image carrier supported at the body;
• a power supply member;
• a supporting member;
• and
• a developer cartridge attached to and detached from the image formation device, the developer cartridge including:
• a developer carrier;
• an input gear rotatable about a rotating axis, the input gear communicating with the developer carrier;
• an electrode member that is electrically connected with the developer carrier, the electrode member including a first contact where the electrode member contacts the power supply member;
• and
• a supported member that includes a second contact where the supported member is supported by the supporting member,
• wherein an imaginary plane is defined orthogonal to the rotating axis of the input gear, the imaginary plane including projections of the input gear, the electrode member, and the supported member, and
• an imaginary line is defined as connecting the first contact and the second contact in the imaginary plane, the imaginary line passing through the input gear on the imaginary plane, where the input gear is located between the first contact and second contact in the imaginary plane.
