Classification: CPC G | IPC G

Claim 0:
1. A cartridge comprising:
a photosensitive drum rotatable about a first axis extending in a first direction;
a developing roller rotatable about a second axis extending in the first direction;
a casing;
a storage medium including an electric contact surface, the storage medium storing information regarding the cartridge, the electric contact surface being closer to the developing roller than to the photosensitive drum;
an elastic member extending in a second direction which crosses the electrical contact surface, the elastic member configured to be compressed or stretched in the second direction between a first state and a second state;
a holder including an outer surface positioned toward a side of the holder in the second direction, the electric contact surface being positioned at the outer surface, the holder being movable with the electric contact surface between a first position and a second position in the second direction relative to the casing,
wherein a length of the elastic member in the second direction is greater in the first state than in the second state,
wherein the electric contact surface is in the first position in a state where the elastic member is in the first state,
wherein the electric contact surface is in the second position in a state where the elastic member is in the second state,
wherein the electric contact surface is outside of the casing both in a state where the elastic member is in the first state and in a state where the elastic member is in the second state, and
wherein a position of the electric contact surface relative to the casing in a case where the elastic member is in the first state is different from a position of the electric contact surface relative to the casing in a case where the elastic member is in the second state.
