Patent attributes
A developer cartridge is attachable to and detachable from an image forming unit. The developer cartridge includes 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 a power supply member provided in the image forming unit, a supported member that includes a second contact where the supported member is supported by a supporting member provided in the image forming unit, an imaginary plane orthogonal to the rotating axis of the input gear is defined, the input gear, the electrode member, and the supported member being projected in the imaginary plane, and an imaginary line that connects the first contact and the second contact in the imaginary plane is defined. The imaginary line passes the input gear on the imaginary plane, and the input gear is located between the first contact and second contact in the imaginary plane.
