Claim 0:
1. A cartridge comprising:
a photosensitive unit including a photosensitive drum rotatable about a drum axis and a first frame supporting the photosensitive drum, wherein the first frame is provided with a first hole;
a developing unit including a developing roller rotatable about a developing axis and a second frame supporting the developing roller, wherein the second frame is provided with a second hole; and
a first pin inserted into the first hole and the second hole such that the developing unit is coupled with the photosensitive unit and is rotatable about a rotation axis to move with respect to the photosensitive unit between a contact position where the developing roller is in contact with the photosensitive drum and a separate position where the developing roller is separated from the photosensitive drum,
wherein, in a state where the photosensitive unit is in a predetermined posture, (i) the developing roller is disposed above a horizontal line passing through the rotation axis and (ii) a vertical line passing through the rotation axis is disposed between a position of the developing axis when the developing unit is in the contact position and a position of the developing axis when the developing unit is in the separate position when viewed in a direction of the rotation axis, and
wherein, in the state where the photosensitive unit is in the predetermined posture, the developing unit is movable from the contact position to the separate position by its own weight.
