A cartridge includes a developing roller rotatable about an axis Lof the developing roller and a coupling member for receiving a driving force, with the coupling member being operatively connected to the developing roller. A first urging member is contactable to the coupling member, with the first urging member being configured to urge the coupling member in a first direction. A second urging member is contactable to the coupling member, with the second urging member being configured to urge the coupling member in a second direction that is opposite to the first direction. The first and second urging members are simultaneously contactable to the coupling member.
