摘要： A drum cartridge, to which a developer cartridge containing toner therein and including a memory medium with an electric contact is detachably attached, is provided. The drum cartridge includes a photosensitive drum; a drum frame to receive the developer cartridge; a lock lever configured to lock the developer cartridge to the drum frame; a first drum contact configured to be in contact with the electric contact in a state where the developer cartridge is locked to the drum frame; and a spring configured to urge the first drum contact toward the electric contact. In the state where the developer cartridge is locked to the drum frame, the first drum contact is pressed toward the electric contact by an urging force of the spring.

摘要： In a developing cartridge, a developing roller extends in a first direction. A developing roller gear, a coupling, and first and second idle gears are positioned at an outer surface of a casing. An agitator gear has an end face in the first direction facing the outer surface. A first protrusion is positioned between the end face and the outer surface, and at a position outside of addendum circles of the developing roller gear, coupling, and first and second idle gears. The first protrusion is pivotally movable about an axis extending in the first direction between a first position and a second position. A first protruding portion has, at the first position, a first length in a second direction connecting the developing roller and the first protruding portion, and has, at the second position, a second length different from the first length in the second direction.

摘要： A drum cartridge includes: a drum frame to which a developing cartridge including a storage medium having an electrical contact surface is detachably attachable; a photosensitive drum; a transfer roller; and a conveying roller. The drum is rotatable about a first axis extending in a first direction and positioned at one end portion of the frame in a second direction. The transfer roller is rotatable about a second axis extending in the first direction and in contact with the drum. The conveying roller is rotatable about a third axis extending in the first direction and separated from the transfer roller in the second direction. A first opening of the frame is positioned between the transfer roller and the conveying roller in the second direction. The electrical contact surface is exposed to an outside through the first opening in a case where the developing cartridge is attached to the frame.
