Developer cartridge having developing roller

摘要

The developer cartridge includes a developing roller, a supply roller, an input gear, a developing roller gear, a supply roller gear, a first intermediate gear, and a second intermediate gear. The input gear is inputted with a drive force from an outside. The developing roller gear rotates about a first axis to drive the developing roller by the drive force. The supply roller gear rotates about a second axis parallel to the first axis to drive the supply roller by the drive force. The first intermediate gear rotates about the second axis. The first intermediate gear engages the input gear to receive the drive force therefrom. The second intermediate gear is engaged with the first intermediate gear and the developing roller gear so as to transmit the drive force from the first intermediate gear to the developing roller gear.
