Abstract
A developing cartridge includes a casing, a developing roller rotatable about an axis extending in a first direction, a developing memory having an electrical contact surface, an agitator, an agitator gear rotatable about an agitator axis together with the agitator, a holder holding the electrical contact surface, and a plate movable between a first position and a second position in a second direction crossing the first direction relative to the casing. The holder is movable relative to the casing in a third direction crossing the first and second directions between a retracted position and an advancing position. The holder is movable from the retracted position to the advancing position in response to a movement of the plate from the first position to the second position. The plate is positioned farther away from the developing roller than the agitator gear and the holder are in the second direction.
