Title: (EN) Developing cartridge
Abstract: front page image
(EN)

A developing cartridge may include: a casing to accommodate developer; a storage medium including an electric contact surface; an elastic member extending in a first direction crossing the electric contact surface, and configured to be compressed or stretched in the first direction between a first state and a second state; and a holder including an outer surface positioned toward a side of the holder in the first direction, the electric contact surface positioned at the outer surface, and movable between first and second positions in the first direction relative to the casing. A length of the elastic member in the first direction is greater in the first state than in the second state. The electric contact surface is in the first position when the elastic member is in the first state, and the electric contact surface is in the second position when the elastic member is in the second state.
