1. A cartridge comprising:
a photosensitive drum having a rotational axis about which the photosensitive drum is rotatable;
a drum flange connected to an end portion of the photosensitive drum;
a developing roller having a rotational axis about which the developing roller is rotatable;
a casing rotatably supporting the photosensitive drum and the developing roller, the casing including a bearing member, the bearing member being provided at an end portion of the casing in a direction of the rotational axis of the photosensitive drum and rotatably supporting the drum flange, the bearing member including a projection that projects in the direction of the rotational axis of the photosensitive drum and away from the photosensitive drum, with the projection including an outer surface facing away from the rotational axis of the photosensitive drum and extending at least partway about the rotational axis of the photosensitive drum; and
a lever supported by the casing at the end portion of the casing and movable relative to the casing, the lever including a force receiving portion configured to receive a force to move the lever relative to the casing,
wherein the lever is movable to a position at which a distance from the rotational axis of the photosensitive drum to a part of the lever as measured along a line perpendicular to the rotational axis of the photosensitive drum is shorter than a distance from the rotational axis of the photosensitive drum to a part of the outer surface as measured along a line perpendicular to the rotational axis of the photosensitive drum.
