1. A cartridge configured to be attached to and detached from an apparatus body of an image forming apparatus, the cartridge comprising:
a first unit including an image bearing member configured to rotate about a first axis; and
a second unit including a developer bearing member configured to rotate about a second axis and to bear and supply developer to the image bearing member,
wherein the second unit is swingable with respect to the first unit, about a swing axis that is parallel to the first axis, between a contact position in which the developer bearing member is in contact with the image bearing member and a separated position in which the developer bearing member is separated from the image bearing member,
wherein the second unit includes a pressed portion to be pressed by a pressing member of the apparatus body, and the second unit is configured to move from the contact position to the separated position in a case where the pressed portion is pressed,
wherein, in a state where the second unit is positioned at the contact position, when viewed in an axial direction along the first axis, (i) the swing axis and the pressed portion are arranged on opposite sides of a virtual straight line connecting the first axis and the second axis, (ii) the pressed portion, the swing axis, and the first axis are arranged in the named order in an interaxial direction from the second axis toward the first axis along the virtual straight line, and (iii) a distance from the pressed portion to the swing axis in the interaxial direction is longer than a distance from the swing axis to the first axis in the interaxial direction,
wherein the first unit includes a cover member that forms a first side face portion on a first side of the first unit in the axial direction and is configured to rotatably support the image bearing member,
wherein the second unit is configured to be swingably supported by the cover member, and
wherein the pressed portion is arranged between the cover member and an end portion on a first side of an outer circumference surface of the image bearing member in the axial direction.
