1. An image forming apparatus comprising:
a main body including a pressing member; and
a developing cartridge detachably mountable to the main body, the developing cartridge including:
a developing roller configured to contact a photosensitive drum, the developing roller being rotatable about a rotational axis of the developing roller,
a developing frame provided with a toner accommodating chamber, the developing frame including a first end portion with respect to a direction of the rotational axis of the developing roller, and a second end portion that is opposite to the first end portion with respect to the direction of the rotational axis of the developing roller,
a pressed member,
a spring urging the pressed member,
a member provided at the first end portion, the member provided with an opening,
a developing coupling provided at the first end portion, the developing coupling configured to receive a driving force from the main body, and
a gear provided at the second end portion and a rotator to which the gear is attached, the rotator being configured to transmit the driving force from the coupling to the gear,
wherein, in a state where the developing cartridge is detached from the main body, at least part of the pressed member is exposed from the opening, and
wherein, in a state where the developing cartridge is mounted to the main body, the pressing member presses the pressed member such that the spring is compressed.
